If Trump continues to push for eliminating income taxes, he will garner votes on that, too. Upper middle class and above would be the main beneficiaries of that (the more you make, the more you are taxed), so that would be pretty cool. I'd love to have a few more thousand each paycheck.
However, he says he will replace income taxes with larger tariffs on foreign goods. This is an inflationary nightmare considering we don't make anything here anymore. This will likely cause all sorts of price increases on various goods, especially those at big box stores like Walmart. Food prices will probably rise as well if those tariffs include imports from Mexico, and there is a SHIT ton of imports from Mexico (veggies and fruits, avocados, et cetera). I would hope those tariffs would not include food, but chances are they will, and Trump will probably use that as leverage on the border issue. It would definitely be a time to buy locally as much as possible and don't go to the garbage big box stores. This will of course hurt the poor and middle class again.
So basically, people will have more money, but inflation will probably remain rampant on everything apart from gas (since he will open up drilling, which is good), while the value of the dollar is raped again. The lower income people who love their Saturday mornings at Walmart will be fucked, but hey, they're stupid for shopping there anyway. The name of the game will be: buy local and buy stocks/commodities/crypto.
