It's quite ironic that you say that "economic systems should serve humans" but then support "tariffs" which will significantly increase the cost of living for the aforementioned humans.
Those are two different groups of humans we are talking about.
Cheap labor benefits consumers - primarily older people who are using savings (workers get higher prices as well, but they also get higher wages, so they're likely to win on net). Tariffs benefit domestic industries at the expense [primarily] of the people on savings/fixed incomes.
