Capitalists are implementing a border solution to correct a shortage in desperation at the workplace. Illegal aliens are perfect for them because they can't claim unemployment so they must be extra subservient. If they become political, hey you are here illegally, off you go.
Bussing them isn't a political stunt by the Republicans either. They are seeing to it that they reach areas where they can plug desperation shortages faster.
Not saying build the wall but that must be something we must be aware of and acknowledge that it is being done to drive up unemployment as Americans are replaced by more desperate people.
One way to address this other than closing the border and mass deportation would be to advocate for the rights of illegal aliens, such as entitling anyone who is employed to the same rights as Americans and a stay on deportation of X months if they have been employed generating profit.
Of course many leave because they realise how badly exploited they are but many more come lining up for work than are leaving.
