A couple of points
By reading HN, we tend to get exposed to world class achievements and improvements leading to a high bar to measure our performance. This can lead to stress, anxiety and feelings of burnout.
The other point is while capitalism has numerous advantages and benefits, I do think it may miss some uncosted externalities (Modern western societies have a tremendous impact on the planet which is hidden from market pressures as exploits different resources). Other examples are the cigarette companies hiding evidence about lung cancer and oil companies hiding research into climate change.
If you purely select for profit and no other criteria, it can tend to nasty effects for others
