The article talks about young men playing video games excessively. A contributing factor is that online dating women are looking for the top 5%-20% or so of men now (combination of appearance and hypergamy), so the bottom 80% to 95% are not dateable online.
(A recent survey said women are only interested in the top 4.9% of men in dating apps, versus the previous estimates of 10%-20%. This is called unrestricted hypergamy and has horrible consequences for both women and society at large, as those 4.9% of men essentially have harems of short-term relationships because they can, and the other men can just play video games.)
I've never heard somebody say, "I want to accumulate the fruits of workers' labor", so I think the understanding of motivation is backwards - it's to create a company or solve a problem, and if workers are needed, you hire them. This is HN, so for most readers should be obvious.
The deeper psychology is that most men need a purpose in life, and a startup is very purposeful. Whether it succeeds or fails is kept by financial score, but it still serves the purpose of getting up daily, focusing on tasks, and trying to "make a dent in the universe." (Richard Cooper)
