Yes, it would make everything else more expensive. I think anyone who has contempt for the capitalist system is confusing politics with economics, tbh. As for need, by definition everyone needs it, since it is to cover items most certainly used by every human being (food, water, shelter, clothing, healthcare, etc). I guess you must mean "need" as in "can't afford because I take more than I give",
No, I didn't mean that. I mean that if a guy can earn his life on his own already, he doesn't need your help or your money to afford the things you're talking about. That's what I meant. A man who is not poor does not need the basic income you're promoting.
But maybe I had your proposal confused with an other in my country. You want to give this money to everyone, including people who actually already have a job and no financial difficulties, don't you?
