I can’t fathom any reluctance coming from the left with respect to unionizing and providing necessary health services to any worker. If people do need to resort to sex work to make a living, then what are they supposed to do when they get older? Do you have to do a “respectable” job just to have the right to …retire? I feel some arguments come from a cruel place.
You might have a different type of person in mind than other commenters. Most commenters had such people in mind who won’t install a password manager or an ad-blocker, or won’t hard reboot their Windows unless supervised. Having said that, I don’t think that even if you had technical people in mind this fits the question. They tend to take substantial more effort to learn and use effectively than the scope set by the original question. I thought this question was for little things that have a quick, lasting, and substantial effect. Learning awk and sed is a different thing entirely, I think of those more as productivity tools you can invest in mastering, and pay off in the long run.
