Paying every adult in the US $26,000/year would cost you $6.2 trillion/year. Your plan would be another $1.5 to $2 trillion a year more than that (depending on exactly how many people live in the high cost of living areas.)
That’s already double the entire Federal budget. Eliminating Section 8, SNAP, etc.. nets you back a couple hundred billion but you wipe that out with Medicare expansion.
And then your tax plan would reduce Federal tax revenues instead of increasing them.
So where does the magic fairy dust come from that pays for this plan?
