Yes it's a taxes issue, because that's how you pay for European-style safety nets. And again that's probably not enough either, cause Denmark/Netherlands are having issues with housing causing the far-right to surge. So you probably need Vienna-style public housing too. The US is so far from the correct solutions you're not even on the same planet.
This has nothing to do with funding.
The US is spending $892.6 billion on the military, $11.3B on ICE, and planning to spend $400 million building a fucking ballroom.
It's about authoritarianism.
