The Finnish plan is not a proposal of new taxes, it's the opposite. It's an experiment they are trialing to use the EXISTING funding, to achieve better outcomes, and potentially to cost taxpayers *less*.
It basically takes the payments from all the myriad of convoluted, fraud-prone, etc., bueracratic systems in place that deal with unemployment, welfare benefits, food stamps, etc., (or whatever the Fin equivalents are), and combines it into one single payment, tied to an individual, if they are unemployed. (It's only going to unemployed in this case, likely due to Right-wingers changing it to be about *jobs*). The idea is to dramatically reduce all the government money spent on managing all those separate systems and enforcement and verification, etc., into one easy to manage payment. Reduce government largess...you'd think the faux-libertarian types would be all over it. After all, it's just a trial of this...it's not some big seismic change anyway.
One payment, more easily managed, it does NOT incentive having lots of babies as TurtleDude is offended at the sub-humans procreating without his approval. He'd be for it in that case? Nah, why bother to read!
It does not "steal more from the rich", or whatever the broken-record libertarian-esque posters claim, this particular trial is taking existing funding and spending it in what they hope will be more efficient for everyone overall.
It's not really a universal income/basic income at all, it's more of an unemployment benefit in this case. They are testing in what is a complex system, to see if they can achieve better outcomes.
You basically list the pros/cons of the current system, and they have proposed a system that in discussing it with sensible people, may have more in the pro-column, and fewer in the con, than the status quo.
It's a trial with just 2000 people (maybe too small), it's a very, very *conservative* investigation into a more efficient government that is designed to promote productive employment.
But here we have the clown car of usual suspects talking nonsense about a proposal they never actually took the time to read. No wonder we have a moron like Trump in office.
