To get a job at Walmart, you have to speak English. To get a job on a farm, you have to speak Spanish. Farmers could automate with robots, but government free market interference prevents it. Go after farming and food production first. Keep in mind, for every $1 spent on welfare, another $1 goes into the pockets of a Democrat government employee to administer those benefits. They are not going to give up their easy ride without a very ugly fight.
It isn’t just democrats benefiting from this. You are blind if you don’t see how much the welfare state benefits corporate America. Having your workforce subsidized by the welfare state is great for profits
