You are arguing more with an imagined opinion and worldview than you are arguing with the comment that you replied to.
The comment you replied to refers to the perceived difference between what "the startup mythology" promises and the reality that many software engineers at startups are given in hard benefits.
Some software engineers at startups work 100-hour weeks because they think they will receive massive compensation in the form of stock. They perceive the stock they have already received to provide a much larger amount of raw wealth than it would if they crunched the numbers. They perceive that their company might provide them with much larger grants of stock if they perform exceedingly well in building the product. Sometimes their bosses guarantee them that they will receive a massive cut of the company, if they just work a little bit harder for a little bit longer.
I don't know how common situations similar to the above are, but they do exist. I imagine many folks reading Hacker News have been on one or both sides of the table in that situation (stock-granting and stock-receiving). I believe that is what the comment you responded to is criticizing.
Nowhere was there a comparison made to victorian textile workers.
Nowhere was there a claim that '(not) getting as rich as you thought' was the worst complaint about the software industry.
You made the latter two arguments up, and then knocked them down.
