From my perspective, though, the original article is talking about everyday engineers (the "technical team"). If you're an early, senior engineer at a startup, you might be offered 1% of the company. Over the early years of the company, you're often critical to the success and velocity of product development - usually just as critical as the technical cofounder. After four years, your company is acquired for $1B! Your 1% has been diluted to 0.75%, so you walk away with $7.5M. After long-term capital gains, you pocket a bit more than $6M. Objectively, you're now very wealthy - if you're still relatively young, this is enough money to buy a nice house, fund your retirement, and do some angel investing, even in the most expensive cities in the US.
Meanwhile, the technical cofounder walks away from the same story with $200M tax-free. That's dynastic wealth. Does the founder's additional year of work justify this difference? What about the partner from your primary VC, who's likely to personally take home tens of millions despite doing nothing more than investing other people's money and sitting in the occasional meeting?
This is the rosiest scenario - the engineer, founder, and VC all earn life-altering amounts of money. Things get much worse if you're a less senior engineer, you're hired after the first large round of funding, or (especially) the company's exit isn't as good. In all those situations, the founder and VC still get a life-altering windfall, while the senior engineer might barely get enough to retroactively bring their salary up to market rate.
