Getting stuff cheaply doesn't destroy an economy.
Saying that we are "dependent" on those cheap goods is just another way of saying that we benefit from them economically, and ceasing to get them would remove those benefits. Of course we could still get by without those benefits, but we stand to gain nothing by having our own government intervene and try to push us to forego them via tariffs.
All of you who are supporting tariffs are supporting something that makes us worse off, under all circumstances, irrespective of what any other foreign governments do.
