For people pro tariffs, I am going to try and break this down as simply as I can for you:
The American manufacturing industry was exported overseas to take advantage of cheap labor (when you want to consider that bad or good is a matter of perspective, as it lead to the greatest economic expansion in global history, but at the expense of certain industries).
Let's assume you bring those industries back - there is a time cost, & infrastructural cost to bringing those sectors back online. Does it create jobs for Americans? Yes, but not without severely hurting the American consumer.
The age of consumerism and accessible goods proliferated precisely because we could produce those goods with cheap labor. If you pay "fair wage", you are going to double or triple the cost of these goods. Inflated wage rates is what ultimately killed domestic automotive manufacturing.
ALL of these extra costs will be passed onto the consumer. Some may argue that with more jobs and better wages, it will allow for increased affordability, but history shows us that simply paying people more can do more harm than good. Increasing minimum wage as an example has actually shown to have a *negative* impact on people, as the price of goods goes up at a disproportionate rate relative to the increase in wage.
Unless you plan to pay people slave wages, in a best case scenario, Americans are paying significantly more to bring manufacturing industries domestically.
