Any system using hard currency has to be partially debt-based as well.
Hold on a second. We need to clarify a couple of your terms.
First, debt-based for whom, the government, or citizens? I designed a theoretical fiat-currency system that is debt-based for citizens but not the government.
Second, when you say "hard currency" I must say I don't like that term at all. To me you can't say hard currency if you're not talking about hard backed, as in backed by a precious metal.
The Wikipedia definition for hard currency even points out this danger:
http://en.wikipedia.org/wiki/Hard_currencyWhat you mean by governments spending debt-free fiat into existence is, for example, if a government decided to build a bridge and other infrastructure for the public good. The government then paid contractors to hire workers and complete all the work. The money then enters the economy. Unfortunately, however, government is a natural magnet for corruption and abuse. So those with favorable influence over government can benefit disproportionately.
But this is the way it works anyway, so the only difference it probably makes is one has bankers at the helm, the other has large corporations.
I designed a theoretical system where neither bankers or corporations is at the helm.
If you have inflation, the ones that get the money first always benefit more than ones getting it later. Inflation saps purchasing power, and I don't see how that can be argued to be a good thing.
Because we witnessed the power of deflation with the great depression. Why this little nugget is so easy for deflationistas to forget is beyond me. Inflation saps purchasing power only because there is a preference to who receives new money first. Deflation doesn't have any shame in saying it is those who have money who benefit.
The effects of the Great Depression came from
inflating before (the roaring 20s) culminating in the crash of 1929. Deflation in that case had a cleansing effect on the market allowing it to move on.
Deflation has no shame in saying those who have money benefit... What are you saying exactly? There shouldn't be a benefit to having money? What use would money be then? As least with deflation even if you have
little money you can rest assured the value you have will be the value you expect, at a minimum.
No, salary doesn't go down in a deflationary economy. No boss will walk into your office and say, "Your groceries are going to cost you less this month, so I'm cutting your pay". That doesn't happen. Deflation means job opportunities decrease, but it doesn't affect people who have jobs, unless it gets to the point they lose them totally.
One way or the other, "more people can buy cars" is a complete falsehood. Salaries reduce or people get fired. Assuming a healthy economy aware of the deflationary aspects, salaries would have to go down over time just like many now receive a typical 3% cost-of-living raise every year.
No, it's not a falsehood.
*sigh*
Let me break it down for you.
Say you have a town, call it BoomTown. In BoomTown there are 100 residents and all they have is the clothes on their back and the houses they built.
One day somebody discovers gold in a nearby mountain and a mining rush begins. As it happens there are only 5,000 gold nuggets total in that mountain, and every resident is only resourceful enough to mine about the same as others. After time each resident has 500 gold nuggets.
These residents have different skills. Some are seamstresses, some are farmers, some dentists, etc. They begin trading the gold as currency for other valuable goods and services - economic exchange.
One day a stranger named Bill pulls into town towing a fleet of cars, left to him by a dying uncle (I guess). He sets up a car dealership on the edge of town. The only things Bill has are his clothes and his cars. He needs food from the farmers, he needs his hair cut, his teeth cleaned and worked on, etc. He has no gold so he figures he will trade cars for some, then he can purchase things he needs, including a house.
Bill has about 10 cars. A house costs about 500 gold nuggets - the entire wealth of a resident on average. Bill figures he will price his cars at 100 gold nuggets each, because that way he can afford approximately 2 houses, or maybe one luxuriant one (of course, then he'd be broke). At 100 gold nuggets per car many residents are hesitant to buy from Bill. They prefer to walk than part with 1/5th of their wealth.
Since this town is called BoomTown it draws in settlers. About 300 people arrive one day exploding the population 4 times higher.
Now we get
deflation.
The same amount of currency exists but there is increased demand for it. That makes the value of the currency go up. People are willing to sew, or perform dental practice for
fewer gold nuggets, because they need nuggets.
What does that have the effect of? The people with the gold nuggets are now
richer. They can get goods and services, like buying groceries, for less. If you're
suddenly richer you will probably spend money more freely... Don't have a car? Buy one. Even if it costs 100 gold nuggets, you can now afford it because everything else now is
cheaper for you.
So, yes,
more people can and will now buy cars. All of Bill's stock of 10 cars will sell overnight, and there will be demand for more!
