I not only deny this narrative that globalization has "economically and socially" fractured the U.S., but also would like to note that most people in modern America are not financially struggling to the degree that populists or free trade-haters claim.
Yes, housing in the most sought-after areas of big cities is expensive (blame lack of building, regulations, rent control); higher ed is rife with federal government-distortion that allows costs to balloon (but going to an elite, expensive school for 4 years isn't forced on you)
medical debt can be a huge problem (negotiate your bills always, and blame insurers, lack of pricing transparency); childcare costs are insane (but there's something innately costly about care work, so it's not clear how to totally drive that down; you don't have to outsource)
but by and large, Americans have very good quality of life. 65% of us own our own homes (though age of first-time home-buying is rising, which tracks with age of first marriage and age of having first kid rising too!)
Median household income is, what, $80K per year? The middle class is shrinking, but not because people are descending into poverty (tho some percentage are); because people are ascending to upper-middle-class to a greater degree than before.
I just don't think the narrative of "Americans have lost big-time from globalization" is correct at all. There are downsides for some sectors, but there are also massive gains not worth taking for granted. It's easier than ever to afford the goods you need to run a household!
The sectors that most contribute to Americans' financial struggles––housing, childcare, medical, higher ed––should be reformed; but protectionism won't do that for you, and will in fact just make provision of basic household goods far harder.
