Tariffs don't inherently cause inflation.

The noise about inflation is very likely propaganda trying to focus people on something that the government can control. (Yet, it looks like the US government is giving up on controlling it.)

Instead, tariffs have complex effects on the real economy. Universal tariffs do cause the concentration of wealth the GP was talking about (but it's way worse than the GP's claim) and deindustrialization. Inflation may or may not happen, it's not a given.
