Let’s do some quick math:
If we paid 250 million people $12,500 per year, the US would spend roughly $3.1 trillion on that single program. Tax receipts for 2015 were at roughly $3.4 trillion on a federal level and that amount again if you account for State and municipal revenues. Total GDP sits at around $20 trillion per year, and total annual wages are around $11 trillion per year.
The notion that spending the entire federal budget on welfare programs is asinine. Tax receipts are already over 31%. A single federal program like the UBI would cost the Federal Government almost what they bring in annually, and I still only used the 250 million figure assuming adults would be the one’s receiving it. Add children into the mix and the figure eclipses rational thought.
