A 10% value-added tax in 2020 is estimated to have potentially raised $842 billion, rising to an average of $1 trillion in annual revenue over the following decade.

Paying out a UBI equal to the VAT rate times twice the poverty line (roughly $2,500 per person), the VAT would still raise an additional $247 billion per year. If the UBI were cut in half, the VAT would generate an additional $545 billion per year.
