You've probably heard the news by now: Social Security, America's top social program, is in some pretty big trouble.

Every year, the Social Security Board of Trustees releases a report examining the program's short-term (10-year) and long-term (75-year) outlook. For the past 35 years[1], it's been cautioning Congress that long-term revenue creation would be insufficient to cover program outlays. In the 2019 report, the Trustees forecast a $13.9 trillion cash shortfall between 2035 and 2093, using the intermediate-cost model.

While the program has three ways of generating revenue, the 12.4% payroll tax on earned income (wages and salary, but not investment income) ...
