"Just find US suppliers."
It's not that simple. There are a lot of things that simply aren't made in the US. (The majority of tool steels, all titanium alloys, everything made of tungsten, and I could go on all day.)
Besides, dealing with the Chinese is like life on easy mode. Handshake agreements are always respected. In most cases service and support are 24/7. Importantly for QoL, they never make you fill out a dozen forms, pay for a D&B report, "let's get on a Zoom call to touch base," and all of that nonsense. American B2B firms aren't really into customer service, as a general rule, I think.
