It hasn't been enough to outweigh all the other absolutely horrible stuff, but it is one thing.
I am concerned that Biden will return us to the old days of "free" trade that allows corporations to import totalitarianism via near-slave or even actual slave (see Uyghur prisoners and forced labor) wage arbitrage to crush domestic wages and liquidate the middle class. This isn't even getting into the export of environmental destruction ("out of sight out of mind") or the export of American technological expertise to unfriendly totalitarian states.
H1B programs can be shady this way too. It's not as shady as actual slave labor or near-slave sweatshops, but there is certainly a serious power imbalance when your employer can pay you sub-standard wages and threaten to cause you to be deported if you don't keep your head down.
