That's just voluntary taxes. Which is hilarious because we all know the only people paying into that are the same crowd that bitch about taxes.

Either that or it's just another way to bribe Trump and they have no intentions of using that money to pay off the debt.

Edit: I did the math and if every American in the entire country donated $50,000 it would still only cover less than half of the debt. At the average yearly salary it would take one person over 700,000,000 years to pay it off themselves.
