Kick the 20 million illegal aliens out.
Or maybe...keep the 20 million illegals and make them into tax payers by updating the current tax code and go to a fair tax...a flat rate of 17 to 23% on what we purchase...current non taxable (food) consumables would be tax free.
Imagine what you would do if you had an extra $1000 a month in your pocket...assuming approx 60K per year with standard deductions!
Or how about the 40 million plus tourists that visit the US...whay not make them pay their share when they visit...they make us pay when we visit Europe and have for 30+ years.
