It was just a quick example video, which shouldn't matter whether AOC was mentioned or not.
But saying you want to pay no income tax in an earlier post is what I've been responding to. If you're ok with paying income tax but want to spend the tax money differently, that's fine but it's completely different.
FYI, if you want the best bang for your buck, money spent on education and infrastructure actually return more money in future taxes than they cost (i.e. they're an investment not just an expense).
