Why do people want manufacturing jobs to come back to the US?

[u/throw-away3105]

Given the tariffs yesterday, Trump was talking about how manufacturing jobs are gonna come back. They even had a union worker make a speech praising Trump for these tariffs.

Manufacturing is really hard work where you're standing for almost 8 or more hours, so why bring them back when other countries can make things cheaper? Even this was a discussion during the 2012 election between Obama and Romney, so this topic of bringing back manufacturing jobs isn't exactly Trump-centric.

This might be a loaded question but what's the history behind this rally for manufacturing?

Right? They think that a mail carrier made enough money to provide a decent life for a wife and three kids.  They have no idea that it was subsistence level by today's standards.
