2. Handle the illegal aliens. Two sub parts to that. 2a is secure the border, whether that means a wall, fence, patrols, or some combination of these. 2b is deportations. Yes we can afford to because we cannot afford not to enforce our laws.
3. Respect the Constitution. That would mean a lot of smaller sub parts such as shrinking the federal government by at least 1/3. Backing it out of our lives by removing regulations, including obamacare. Rescinding every single EO of bammy's might be a good start too.
I'd bet dollars to donuts these indirect actions would help shrink the debt, improve (really improve not just a number game) unemployment, and get the economy growing again.
Begin deportations yes, but also use any constitutional power within reach to remove taxpayer funding for illegals - no welfare, no education, no medical, no ebt cards -nada, nothing.
Those who feel charitable towards the usurpers would be free to donate their own money to the cause.
