The only way that a 10% tariff could bring jobs back would be if the difference between paying someone in the US to do it is less than 10% more than paying someone outside the US to do it. Otherwise it will still be profitable to do this outside the US, and this is just a tax hike on Americans, who don't generally seem to understand that tariffs are taxes.
