That's a good point. Why not let the market determine the best outcome?
Is our "free" market supposed to be for the benefit US citizens or are US citizens just disposable cogs in the global market who can be tossed aside when they lose their utility?
National governments often act like a union for their people, protecting their interests in the global economy.
Our "union" has lost sight of who they are supposed to represent and has been working for themselves and select others.
The people elected a new union boss. If he doesn't get things back on track the people may decide they don't want to be in this union any more.
I spent decades being an open borders global free market proponent libertarian. Decades
being the proponent of a political philosophy that was just as Utopian and just as unworkable in the real world as Communism.
The open borders global market system has supplanted our national identity and culture. A rich common culture of strong families, strong neighborhoods and national pride of being an American. We are losing our identity as a nation, the glue that binds us and our culture has become debased. Our culture is now a hodge podge of the lowest common denominator in every area. A non-judgmental consumer society of hedonists.
