I don't think undoing globalization is going to mean going back to the old ways. Personally, i think those well paying middle class jobs are gone, the status quo is too enshrined in the minds of business leaders, political thought (not just politicians, the populace) and the economy.
The end of globalization will be more of the status quo, but different, not how it was once was in the golden years after WW2. If i had to guess, same global companies, some of the workforce still making 10-100x the average salary but now many of the low-paying jobs simply onshored, maybe even furthering the socio-economic divide because you won't be able to buy an American-made 60" TV for $800 anymore.
