What you are referring to is their inability to see cause and effect. Action and consequence, because they just blame whatever consequences they don’t like on someone else. If communism hasn’t worked in the past, for infinite example, it’s because of capitalists. However, I take partial disagreement with you. I don’t think those receiving entitlements should be taxed on what they’re getting through taxes anyway. Either they don’t get them, or they don’t get to vote while they are. But as you know, once people find out they can vote themselves the forced welfare of others, democracy ends.
Unfortunately, the Constitution guarantees a vote to all citizens, so you can’t deny them the vote. But I do think that they shouldn’t be protected from their own unwise acts.
People on welfare should not be allowed to vote.
