Or because it uses its huge military might to make sure it is so.
Of course. The market only cares for the bottom end.
I'm saying it though for those pretending the market is some victimless activity, that's not about power at all, etc, and "hard working people" (and countries) prevail.
The USD enjoys an unfair competitive advantage over its peers and this distorts the financial markets immensely and more importantly the balance of power in international relations esp. in times of political crises and military conflicts.
The point is that "undesirable wealth distribution" is not what an economic crisis is. If 400 people controlled everything, the world wouldn't be a great place to live, but the economy would probably be more stable.
There's plenty of reason to believe in proletarian revolution [0] as a thing that happens, whether or not one believes in it as a thing which is an ideologically desirable response to certain conditions.
[0] At least, revolution in which the lower classes are actively involved and where their dissatisfaction is a key lever used by the revolutionary leadership, even if the leadership itself is often from disaffected factions of the elites, either in government, military, academia, or private wealth.
