Trump DID do that. About 500,000 new businesses opened with his plan and he gave tax breaks to small businesses that fit a criteria he set so that they can keep more of their profits.
I don’t know why you brought up the wall, I never did. But did you know in 2016 Hillary Clinton, Barak Obama, Chuck Schumer and 23 other prominent democrats were in favor of 700 miles of wall along our Mexican border? Just 10 years later they did a complete 180 and now want all 22 million illegals to be given citizenship. The wall along with stricter immigration laws is necessary to help both us and Mexico and I’ll tell you why. A major reason so many Mexicans are coming here is because the drug cartels are out of control and even overpowering the national guard sometimes. The reason they can is because they are able to sneak into the US, sell their drugs, and then buy very affordable American guns, return to Mexico, and continue fighting. Tighten who gets in, not only will we stop the cartels from profiting in the states, but we will also cut off their ability to arm themselves like they do now. In fact, when stricter immigration laws were put in place, the murder rate actually went down in Mexico. I repeat, down.
