I honestly cannot understand that people (left or right) are still discussing basic income. A simple back of the envelope calculation shows that you have to basically double the tax rate to pay for it. Here are the numbers for Germany, but I'd assume that the situation would be similar for many other countries.

Assume we give each of the 80 Mio germans 10000 Euro per year. That's an expense of 800 Billion per year. Contrast this with a total tax income of ca 600 Billion per year [1]. It's not gonna fly...
