The American dream doesn't *come* from anything, it is a set of ideals that include equality, freedom, democracy and individual rights.
It is equality of opportunity, it is also the lie that hard work will improve your circumstances, it's more complex than that.
You want a Capitalist society? That is always going to involve disparity of wealth.
The original intention was that the wealth created would have a positive impact on everyone.
"Smith was very aware of the inequality markets would produce. In Wealth of Nations, he wrote, “For one very rich man there must be at least five hundred poor, and the affluence of the few supposes the indigence of the many.” Smith also knew, however, that markets had great potential to lift entire cities and nations out of poverty — benefiting the wealthy, yes, but also the underprivileged. For Smith, inequality was worth the “universal opulence” that markets would produce, because the benefits of markets would “extend itself to the lowest ranks of the people.”
Capitalism was created with the intention that the vulnerable would be taken care of.
You are actually criticizing Capitalism.
