It’s the same thing they did with Obamacare. It’s not about trying to actually reduce costs it’s about starting a big government program that they can funnel money to their preferred constituencies.
Personally I’m at a loss to guess what left-wingers’ motives are, but it always comes back to this ‘zero-sum’ mindset that anyone’s wealth creation is somehow ‘wealth-theft’ from someone else, and the only way to raise up the poor is to lower the rich.
That kind of thinking is not historically an American ideal, it’s more a product of poor countries. imho it’s the mindset that makes the poverty.
