“Virtue through suffering” is an interesting take on modern labor. I agree with most of what is posited in the wiki article you posted, but the book was written pre-pandemic and I think that our perspective on our own labor has changed significantly over the past couple of years. Gen Z in particular doesn’t seem to value pointless labor the way the Boomers do and I know many millennials would rather ‘cram and slack’ than do the 9-5 grind.
With the rise of automation our perspective will likely continue to change. I’m hopeful that we will go through a sort of Renaissance era where humans no longer tie their self worth to their labor and we can begin to view industry in terms of providing need rather than creating profit.
