So you tell me that they use tricks to sell you one (good) thing and implement another (bad thing)? And you think they are not going to continue to do that? Specially with somebody at the helm that has been privately doing exactly that for a long time?
The USA will need to compete in the global market to sell its products. That means the USA will need to use globalization in order to find the best place to produce with quality and to be able to compete in price.
So, retreating from globalization is not an option. You can avoid people entering the country, but this is not going to make your country any richer. And that is for sure not going to guarantee that inequality is going to decrease.
For that, you need to tackle inequality directly, by collaborating internationally to avoid loopholes (double Irish and such crap) that steals revenue from countries and concentrates in the hand of the global financial elite.
Trump is not going to do any of that.
