It's true that "dumb" libs aren't able to argue on point because they were not raised in a rational household. But my theory on why the "smart" libs do not argue on point is
1. They don't want to solve fiscal issues. They have learned that that can get much quicker backdoor fascism if they can entice the banks into a bubble with govt policy, the govt will essentially nationalize the (biggest) banks, and a few big corporations. That's what happened in 2008.
2. They don't want to solve the "healthcare crisis". They wanted to use the fear of death and the desire for free care to entice people into Obamacare, which was nothing but a trojan horse to destroy the private insurance industry.
It's about shortcutting to fascism.
