"Original" as in the definition that has been used for the last century or two, and is still being used by economists, as opposed to the weird revision you are using. Specifically this "an economic system characterized by private or corporate ownership of capital goods, by investments that are determined by private decision, and by prices, production, and the distribution of goods that are determined mainly by competition in a free market."
I've bolded the keywords. In laymen's terms, recognition of property, voluntary trade, and uninhibited competition with other traders.
Is this beyond criticism? Is it wrong to criticize the way it has been put into use? To point out the obvious flaws?
Of course not. As long as you point out the flaws in the system itself, not point to unrelated things and claim that they are the system. I.e. saying "Capitalism is bad because it fails to address this crime" is ok. Saying "Capitalism is bad because this crime is capitalism" is not ok.
Are you saying that all economists think alike- or just ignoring all nonclassical economists?
I am saying economists try to establish an agreed-upon definition of terms before they start deriving economic theories and debating each other. It's hard to set up a Supply/Demand graph when some people decide that "Supply" means the supply of need instead of supply of products, for example.
When you say "recognition of property" who on earth are you talking about?
Me, you, everyone. We all recognize that we own the things we have, almost from birth. Moreso, we recognize that we own then in spite of laws that may say otherwise. It's why people get upset when government comes in and "legally" seizes their property, such as in imminent domain cases to use for building malls, or in nationalization cases.
Is it not the supposed job of the violent state to do this?
Violent state can help enforce it, just as violent individuals and violent private security firms can help enforce it, but that's all they do - enforce. They don't actually create the concept of property; the concept of "I own this because I made it myself using my own stuff."
What about those who recognize all resources as commonly owned?
Difference of opinion? It's ok if the resource in question is just commonly owned and shared by everyone who owns and shares it. It would be a big problem if someone rightfully feels like the own something, and then a bunch of other people start coming in and claiming ownership to it too. That's when violence may come in, from state or otherwise.
Certainly this is a fair viewpoint, and one capitalism actively sweeps under the rug.
Not at all. Corporations are commonly owned. Capitalism just makes sure that there is a set number of owners who are responsible for their ownership, instead of having things be unowned and in a free-for-all.
When you say "voluntary trade" are you not talking about ill-gotten, stolen resources?
Voluntary suggests it was traded voluntarily. Trade means two or more parties. Ill-gotten stolen things are by definition not voluntarily traded away by their previous owners. So, no, I am not talking about that.
The operation of capitalism is exploitative and inefficient according to the definition we agree on.
It's chaotic, that's for sure. As for whether it's inefficient, intuitively it may seen that a central planning body that can oversee everything and determine where resources are used best would be more efficient. In practice, and in history, this was shown not to be the case. The main reason is that when you have an enormous amount of constantly changing information, it's actually more efficient to only allow small groups/actors to work within the small sections of that information to make decisions. A large single planning body just can't process the information fast enough. It's decentralization, and is also why 3D printing and Bitcoin are way more efficient when it comes to giving people exactly and specifically what different people want, instead of having a single unweildy body, like a bank or a factory, produce the average of what people want, while lagging behind changing trends.
Any force that makes most poor and few rich, as it can be seen to have made, is a force that cannot be sustained.
Agreed. The poor will undoubtedly rebel when they get fed up with being treated unfairly. It has happened over and over, with disastrous consequences. But which force are we talking about exactly? Capitalism, that prices goods and labor, and gives people information about whether their skills aren't valued, and perhaps should be changed or improved to get them out of poverty? Corruption and crime, often sustained by governments that pass regulations to help keep their corporate buddies in power and use the police force, paid for by taxing the poor, to keep those very same poor from revolting? Or just plain apathy and laziness of some people, who do nothing except complain about how their lives suck, while doing nothing to change their situation, and just watch their peers take evening classes, working on developing new skills, and quickly leaving them behind, while using excuses such as that their peers were just lucky?
Before you go back into this silly drivel about making toilers rich as well, you might consider at what cost and how often.
We, as a society, make toilers rich all the time through capitalism. Just look at India ten years ago compared to now. People with degrees were earning almost nothing, living in really horrid conditions. Then those same people started getting menial unskilled jobs, working in factories or phone support. Now those people are able to demand pay 10 to 30 times or more than what they used to get, working in research, software development, and engineering. India is no longer an ideal place to hire toilers, because millions of people were raised from the slums into middle class, not because of government programs, but because of market competition. Same deal with China. 10 years ago, people were working in horrible conditions in factories, toiling day and night for little pay, while barely earning enough to survive. Now, even though a lot of the work itself is similar, the working conditions are vastly improved. They are clean, well lit, with much better housing, resembling that of university campuses, instead of shantytowns. Sure, China has a bit to go still, but there's no argument that their toiler's situation has improved as well. And again, decades of communism and social planning couldn't do a thing to help those people out, but as soon as they allowed capitalism, however restricted, and outside companies to come in and compete for workers, things improved dramatically.
