Pure Capitalism would be Wall Street owning the economy.
Pure Socialism would be Washington DC owning the economy.
America has long strived for a middle ground, a balance between billionaire interests and common interests. Back when labor was highly valued these interests made for a nice pair. Americans enjoyed a post-war golden age. Then we opened up Asian markets and laid off American workers. We imported impoverished labor and flooded American markets.
We sank the American wage while cost of living continues to rise. But Wall Street is more profitable than ever. That is "income inequality" in a nutshell. The gilded barons have more profit and more production and the people on the street have less. The symbiotic relationship between laborer and CEO is being abused. The wheels on our economy are breaking.
Economy is liquidity. It is the movement of value throughout a society. We place that value into dollars and make purchases. It used to be that business was simple and value obtained from purchases mostly circled back into wages... government need not apply, not much help was needed.
Then someone, or a group of someones, got greedy. Wall Street kept more of its profits for itself and then offshored that value. They use our purchases NOT to return that value to the American worker but to grow their own portfolio with investments in other countries. Your lost wages are in other countries. The difference between this generation and the Boomers is the money you send to a business is not kept as liquidity for our society.
Thus the symbiotic relationship is either strained or broken.
And in their desperate need, our people turn to the government to replace that lost liquidity. Right now our people are too poor to survive without handouts - and they know it. They simply are not paid as much value as their parents. And at this rate their children will be paid even less.
Whether our people have enough economic value to survive isn't even a matter of Socialism. You don't have to own production to tax production. You just have to maintain a good system that provides enough base liquidity for our people to enjoy decent lives.
