We seem to agree on UBI ideally being a supplement to existing welfare programs. I'm certainly supportive of any of those funding mechanisms you mentioned. The idea of a robot tax is something in particular worth looking into; South Korea implemented a variant of it several years ago which appears to have been a positive, and it would serve as an another counter to automation displacing swathes of people. I admit that I'm attracted to the notion of it truly being universal, but I understand if narrowing the recipients is the difference between passing and failing. Would an income cap of $50,000 per individual muster any interest among the folks in this chamber?
$50,000 sounds good to me, that'd cover around 70% of people.
I'm not voting for this under any circumstances, particularly if it is means tested. Basic UNIVERSAL income means UNIVERSAL income, not just yet another money grab from the so-called rich.
