It fits the narrative of US doing better than everyone else, thus money is flowing in.

There was a study done (can't find the link atm) regarding the impact of the tariffs on US consumer goods, and what they found was that the impact on US goods were negligible. The Chinese suppliers usually ate the tariff cost, which cuts into their margin. This in turn either bankrupts the company - because the private enterprise in China has been suffering from massive debt and government preferences for state owned enterprises - or it prompts the company to move the factories to Vietnam or other places.
