Tariffs to the USA Wealth Fund

The concept: Assign a portion of all new tariffs to the USA Wealth fund. The fund would be invested in USA stocks, to support our great nation by growing its wealth. After achieving a 1 trillion-dollar balance, the fund could make 1 annual disbursement of no greater than 3% of the balance to pay down the national debt, to increase funding to Social Security, and/or to enhance the national defense. Of these 3 choices, the President would decide how to apply the money.
