The main problem with socialism is the centralization, and I my opinion socialism can work on a decentralized system like (blockchain). Now the question is how?
Ok look at miners, let put in perspective and say they work like the gold miners, but still they are a lot different. Gold miners are mining gold a natural resource, where bitcoin miners are just there for security, that is why they get the rewards for every transaction and new btc. For mining Gold, you need human resources, machinery, transport, storage, on another side for bitcoin you need computers and electricity, no transport, and no storage ( 185 gigabytes for September 2018, this is still nothing).
Gold is used mainly for jewelry! The gold standard was once used by many nations, but it eventually became too cumbersome and is no longer used by any nation. Now gold is used for investment, people on the stock market guessing when the price goes up and down, that is it (same as Bitcoin ). Gold is used in manufacturing but not in huge masses.
Ok, now when people say
MINERS = CAPITAL
It is all the perspective how you look at it, what if a small city around (40.000) people, make they own mining farm, everybody invest and everybody gets the returns from the mining firm through their app, now you look at miners like a perspective of a socialist, the more trades happening, the more rewards are giving out. And you have some basic universal income, now it isn't much (it can be in 10 years) but with bitcoin, let not forget, you can access the global market (trading for other coins, tokens). There are cloud mining options but those are trying to make a profit from you, option above is less risky and when executed right can be better than the cloud mining options. Now everyone gets a cut of the global trade. You killed the need for banks, savings billions of dollars, and let us be honest, banks are doing nothing productive for the society. This is way ICO is great, you can access the global economy with few clicks, if you need a credit to start a business, buy a house, etc. Crowdfunding is the future (and crowdfunding in the core of socialism and a little bit of capitalism). Capitalism is not bad, but capitalism and globalism is a recipe for disaster. You can see it by looking at income inequality, lobbying, climate change, wars.
In the end, it is how you see the world, nothing more or less.
