Not to say any country has successfully ended homelessness, but there are at least a dozen successful counterexamples to your claim that those policies would "destroy" economies with taxes.
Are you honestly and seriously suggesting that the US tax system is absolutely at the limit and there's no room to pay for any of these policies? For example, we shouldn't have any more tax brackets over the $400,000 one? Have you looked at the proposed tax brackets that actually pay for these plans? How do you explain the idea that 3 new tax brackets ($500k-2m 43%, $2m-10m 48%, and $10m+ 52%) would destroy the economy? How exactly do people who make $10m+ single-handedly sustain our economy, why would a 10% tax increase on their over-$10m income end that, and why do the thousands of dollars of reduced overall expenses (including taxes) for almost everyone else not matter at all in your math?
