The American taxpayer is the largest employer on earth. There is no reason private companies should be able to outbid the American taxpayer for the smartest, most charismatic, hardest-working problem solvers in the job market. Every day the government shuts down, every elected official forfeits a week's salary — deposited into the Veterans Emergency Relief Fund within 72 hours. Irrevocably. On day four of a shutdown, four weeks of salary has already moved to veterans. Every reporter in America can check the balance every morning.
The figures — $1M, $2M, and $5M — represent approximately one-third of what a comparable private-sector role pays: enough to make the job worth doing for someone who could earn more elsewhere, and the lowest number that makes the incentive argument work.
