UBI isn't inherently different. It's trying to pretend you can manipulate a market with no detrimental side effects, but it's been tried many, many times.
You seem to be of the opinion that nothing can be done to eliminate poverty, so why even try?
Plenty can be done to eliminate poverty. I'm confused why you would think large-scale involuntary wealth redistribution is the only way.
It is, by definition, not a subsidy since it does not target a subset of economic sectors.
> Plenty can be done to eliminate poverty.
Name one means of eliminating poverty without wealth re-distribution or subsidies. The only ones I know of involve sterilizing, deporting, killing or otherwise demographically elminating poor people.
Nobody's eliminated poverty yet, so it may be impossible. We do have ways of fighting it, though, which can (and does) include charitable giving (note: voluntary) and economic development of areas.
