It's an interesting concept...
I assume this is mainly here since it indirectly has to do with politics, etc., which isn't really allowed, but well...
Andrew Yang's the biggest proponent of it that I have read of recently. His idea is to tax 'services' in order to pay for it...
If you are not aware, here there is an income tax, but not a service tax... at least not directly...
so like if you go to a hospital or something you'll pay a copay, and a coinsurance, and possibly a deductible, as well as anything the insurance won't cover (due to any number of made up reasons they create - for example if some insurance says they only want to pay for 2 ultrasounds per pregnancy, they'll pay on the 2, but you'll get the full bill for that third or 4th one, etc.), if you have one, which legally you are supposed to since the president before this one set laws in place for that, etc., which you pay a premium for monthly... but anyways, the Doctor's actual hourly 'service' fee and nurses 'service fee' are not taxed, even though in a roundabout way they kind of are because of how the corrupt insurance industry is well... uh... yes... (most hospitals and clinics charge insane rates of at least 35% markup on everything from the cost of a medication to the cost of a supply including but not limited to the tongue depressors...) ... and all of this is on top of already outdated models of payment like what Medicare and Medicaid use... paying some flat rate no matter what for inpatient services even if that flat rate is more than what the hospital may be charging... so you could have something like some insurance or Medicare pay the hospital or doctor say 500 dollars for something they'd bill only 400 for, and on top of that there's a copay you have to pay too, of oh say 300.00 so your insurance or Medicare will pay 500+you pay copay of 300 for... so 800 paid to hospital for something little ol hospital is only billing 400 for... great system...
so yep, more taxes on already overpriced shit so that everyone can get a free, at least everyone legally here over a certain age, can get free monthly amounts back as sort of a negative income tax, but wait... what the hell...
so uh... yeah... more taxes to pay on top of already paid crap that is way overpaid in the first place... yippiee..
