That's his opinion. Tens of millions of other Americans don't think so at all, and they're making their voices heard in national elections and successfully choosing our leaders.

That would be fine, but it seems that fairly often, once they need those safety nets and not "those other people", those principles no longer apply.

Picking an example disconnected from modern politics...

Suppose that every year the federal government gave each family a baked goose to celebrate our acquisition of colonies via the Spanish-American War. You can think this is an offensive celebration or a crazy waste of money, but why not accept the goose when it is delivered? It's still a tasty meal, even if you think it shouldn't be given out.

That is what is going on. It's not hypocrisy, hate, or inconsistent principles.

Voting in my best interest would necessarily include policies taking things from some Americans and giving it to me. Just because I'm voting in my best interest doesn't mean I'm voting for something good.

What matters is voting consistent with principles even if they aren't in your best interest.

No. You seem to be unfamiliar with the idea that "a rising tide lifts all boats". You're assuming that acting what appear to be your best short-term interests will equate to a better outcome in the long term, which is usually not the case.

For instance, should you vote to abolish police and courts, so you don't have to pay taxes for them? In the short term, that would net you more money. In the long term, it would mean you'll be living in a lawless wasteland and someone will rob and murder you.
