Several of your comments on this thread take words straight from my mouth, but this on resonates especially with arguments I have made about financing a basic income. I feel very strongly that for fiscal, fairness, and political reasons, we should pay for it in full. I would eliminate the payroll tax, increase progressive income taxes to pay for Medicare and SS, and then further increase them to pay for a NIT benefit at the poverty level. I've written a book on the subject that may interest you (https://www.amazon.com/gp/product/B085Q1FL2D/ref=ppx_yo_dt_b_d_asin_title_o00?ie=UTF8&psc=1).
Of course. You seem to take this seriously and may be interested in my book, Social Security Basic Income: A Safety Net for All Americans (https://www.amazon.com/gp/product/B085Q1FL2D/ref=ppx_yo_dt_b_d_asin_title_o00?ie=UTF8&psc=1), which addresses the question @AthKaElGal posed yesterday in the thread that was removed about how to pay for a significant guarantee.
Read all about it in my book, Social Security Basic Income: A Safety Net for All Americans (https://www.amazon.com/gp/product/B085Q1FL2D/ref=ppx_yo_dt_b_d_asin_title_o00?ie=UTF8&psc=1). I propose eliminating the payroll tax, which would freeze benefits, and funding earned payments and Medicare by eliminating most individual tax expenditures (deductions) and making the income tax more progressive (higher for those with higher incomes). That's step one. Step two is raising the progressive income tax to fund a negative income tax type income guarantee of $1000/mo. that would eventually replace Social Security.
