The extra costs support the US government, so opinions will vary. But that's the pessimistic view. The ideal outcome is making import costs high enough that US manufacturing can compete without subsidies.
The ideal outcome is a fantasy. The US doesn't have factories because every large US company currently offshores their factory labor. The tariffs at this point in time just increase costs for consumers while, ideally, US companies build factories on US soil over the next 5+ years. That is not a good outcome for Americans, even considering the support of future American manufacturing.
