Mass deportation of our cheap labor supply will do way more to increase cost of groceries than Chinese tariffs ever will. The cold hard truth of it all is that our entire way of life depends on exploiting cheap migrant labor. Democrats don't like to admit it because we don't like that kind of exploitation, and republicans don't like to admit it because they don't like immigrants. But we depend on them as much as we do the laborers in chinese factories, the somewhat educated cheap labor in India, the children in sweatshops in Vietnam, and so on. Our entire economy is based on exploiting someone, somewhere, artifically reducing the cost of living for us.
