Oi, I realize this will woosh right over your partisan-baked brain, but I'll bite:
"What makes you think that anyone is entitled to someone else's money?"
How did they get that money in the first place? Through a societal system they are able to take advantage of. Never completely on their own like libertarians are want to believe. Our current monetary system is based on debt leveraged on debt based on a promise. It's purely imaginary, fiat, whatever. The real deal is the cost of energy, resource extraction (also a function of the cost of energy), and labor cost (which is decreasing due to automation/globalization). Money is just a convenient shorthand.
"you're trying to impose your beliefs as facts"
I'd like you to meet Kettle, Mr. Pot. Also...notice that I used words like 'could'. It was pretty clear I was speculating, not claiming anything as a fact (otherwise I cite that shit).
"How (who?) defines how much is "basic"? That is a good point. If I'm able to filter out your partisan ObamaPhone/Nike bullshit I can see where you are going (though your mental image of what constitutes a poor person is a hilariously on-message Fox News caricature). Who or what defines a living as basic is a pretty subjective thing. A good place to start is being able to eat real food and have a stable place to live. I'd go so far as to include internet in that mix.
"The problem with Socialism is eventually, you run out of other people's money."
Nice quote there Thatcher. Got any good Rand for me?
"you're so useless, we'll pay you to not work so you will go away and we can ignore you"
That is not the message. The message is "everybody is worth something, regardless of whether or not you are capable of 'meaningful work'. Mentally ill people, physically disabled people, etc.
The value of meaningful work != the monetary value. With a basic income if somebody wanted to make art baubles and somebody else found value in them...how is that less meaningful than cleaning a bathroom at a movie theater?
So, having said that. I'm sure there would be some negative consequences. Since I'm speculating as much as the next guy, what would some be? If people got a basic income, then they wouldn't be forced to work in a Tobacco field for minimum wage (or less in a lot of cases) to make rent. What would happen O sage of the free market? Would the wages for these shitty jobs raise to meet the demand of the no-longer enslaved lower class? Would that then cause the price of cigarettes or whatever else to go up? Would inflation explode to make the basic income essentially worthless? (a possibility smarter economists than I say is unsupported by evidence...no cite though)
Seriously though, Mr. Libertarian, go fucking live on an island. If you want to say 'I got mine, fuck off' so badly, GTFO.
