They also work 400 hours less per year than their US counterparts and 1000 less than their Chinese counterparts.

You might be comfortable in that life, but you won't be competitive.

And pray tell, what does the American or the Chinese worker in this case get out of their higher productivity and competitiveness? Because it really seems that it's not quality of life, that's for certain.

More money and material comforts? Well perhaps, but then again, I do wonder just how many would willingly take that rather than for example a proper work-life balance or clean environment. And we'll probably have to rethink the relationship of our societies with material consumption etc. in the coming decades anyway due to the climate emergency, and so maybe it'd actually be better for the US or China to adopt our "less competitive" stance rather than for us to try to agonise on trying to get ourselves competitive with them.

No one has yet figured out just what one's material possessions will do for them after they're dead. At best you can pass them to your next of kin, but that doesn't need the kind of hyper competitive, hyper capitalistic mindset espoused by the US or China.
