Earlier quoted context omitted.
I think the idea is that tariffs cut both ways. They increase prices for foreign goods as well as reduce demand for imports causing job losses in the exporting country. The original tariffs increase prices and the retaliatory tariffs reduce demand for American products causing job loss.
Yes but since Canada is also initiating new tariffs (they've had existing ones for specific products and industries already) so anything said here applies to Canada as well. For example Canadian tariffs increase prices and their retaliatory tariffs also reduce demand for Canadian products leading to job losses.
Correct. But Canada didn't start this trade war, all it can do is respond to it.
And the correct way to respond to a bully, fraud, and liar is tit-for-tat. Tax his exports, tax your irreplaceable exports. Tax and block his digital and media services.
