Bob and Sally like each other. They like licking each other genitals. They plan to combine their genes and produce viable offspring to propagate their species.
Then government come and say, “Okay Bob and Sally, here is what the deal is.” Bob you got to be loyal with Sally and that means not fucking other females. Sally, you have the right to divorce Bob at will and collect his whole paycheck.
“If that’s what the deal is, I am out,” said Bob. Now, Sally, can’t choose Bob. Sally need to choose some idiots that do not value his freedom, which may not be her best choice. After all, it’s those who are poorer that do not mind risking all his wealth for a girl.

Stupidity is a choice. It’s a choice our genes make because knowing too much have little value and too much danger.
If you’re dilligent, of course, you will agree with whatever argument whose conclusion is lowering income tax. It doesn’t matter if the argument is based on some fairy tales that’s not even relevant anymore.
