alt Hacker NewsNope. Globalism has made America richer than pretty much any nation in the existence of human history.
The election of leaders who prioritize the distribution of wealth from the poorest to the richest rather than vice versa has hollowed out rural America.
And rural America disproportionately votes for such leaders.
Technically you're not wrong, but without globalization, deindustrialization wouldn't have happened and unions (and strike threats) would probably be strong enough to prevent the poor to rich redistribution.
So even if globalization made America richer on average, it also destroyed the fair redistribution mechanism.
