Ok, I can show you where your machine is broken, exactly where it is broken.
Capitalism at base is people trading whatever they have for whatever they can get, at the best prices they can get, or pay. Over time, any capitalist system will produce winners and losers. Some people will be more skilled traders, some will have goods that are more valued than others. They will grow wealthier and wealthier over time.
Generally the people who will rise to the top in a capitalist system will be the ones whose only concern is making more money. After all, capitalism is an ethics-free system, it’s just economics, and does not require that its players act ethically.
Once these people reach the top economically, they wish to remain there. They can do so by competing successfully with others, but they are aware that there are others out there who are almost as skilled as they are at competing in a capitalist economy. If only they could ensure that the rules of the marketplace are altered to keep themselves on top.
Well of course they can, because they have money, and money is a form of power. And they can bribe government officials (or in the US, “make campaign contributions to,” it’s pretty much the same thing nowadays) in WHATEVER form of government exists (not just democracies) to make laws that give them a huge competitive edge. So they do. They don’t care about the general welfare, only themselves, as is proper in a capitalist system.
So any capitalist system will eventually become a simple oligarchy where wealth becomes increasingly concentrated in the hands of a few, to such an extent that the excesses of the oligarchy eventually bankrupts the system and leads to a huge economic disaster that CAN but does not NECESSARILY lead to a “reset” for the system, with the system cooled down for a bit until the oligarchs find a new way to concentrate all the wealth in their own hands, leading to a new crash. Happened in the Gilded Age with the robber barons, happened in the 1920s, and happened in the recent Great Recession.
It’s no good saying that “we will regulate more and better” because the wealthy oligarchs will fight attempts to regulate their activities, however unethical, immoral or even dangerous to the society as a whole, and they’ll succeed over time … because they have money, and money is a form of power.
I don’t know how you solve this conundrum while maintaining a strong economic system, but I’m sure one will come along, and whatever that solution is, whether it is a variant of capitalism or a new economic system entirely, it will supplant capitalism very rapidly … because it will be more efficient than what we have now.
The closest thing I can come up with to an answer would be for economists and governments to recognize this essentially malign and self-defeating aspect of capitalism and start enforcing rules and regulations based on how affluent and successful the capital markets make members of the middle class. Assume the wealthy classes can take care of themselves, and will. Recognize that once successful capitalists become entrenched at the top, they become the enemy, no matter how much they profess to love capitalism. Then pass whatever laws and regulations are needed to make sure the middle class has an equitable share of the wealth of the country … say 60 percent as opposed to the present 2 percent.
However, as sure as I am sitting here, the oligarchs will fight any such program relentlessly, with all the power and wealth they can bring to bear. Which would be … a lot. Probably a lot more than simple intelligence and altruism can bring to bear.
