No I don't. Frankly, I suspect I understand tax and spending a fair bit better than you do, probably because we've spent the past 2 years talking about it in Scotland due to the independence referendum (and the following talks on full fiscal autonomy).
> How many people have any clue as to where tax revenues come from?
Just about every grown adult on the planet? Who do you think pays taxes?
> How many understand that other people have to earn that money first?
Well, that's just plain wrong. You're conflating money and wealth. They're different things. Money is just created to reflect wealth: it's literally just invented by your government (or, in the case of Bitcoin, just by proven work). And wealth doesn't have to be earned; it just has to be created.
> How many understand that if the people who earn money are burdened with much higher taxes to pay for someone else's BI, a lot of them them will just stop working because fuck that?
Sure, I'm going to stop contracting at $3000 a week because, hey!, I could just live on $30 a week instead.
> Please just think about it for a while.
Yes, please do. There are actually intelligent objections to BI.
Here are some proper concerns: What about illegal immigrants in the country? What about the federal government having all your details if you want to claim BI? Would it be better to be state run than federal (or in the EU, by countries, or would it be better run as an EU project?). Would it create problems with inflation? Would it cause problems with the banking system?
