Assuming "we" are all engineers. There's no reference to role in the article or comment you're replying to, so I don't think that can be assumed. There are plenty of low wage jobs at startups.
If the frame of reference is "anyone" then I still don't get the argument. What percentage of jobs out there are lottery tickets? A tiny, tiny fraction. So what's the advice from the GP; everyone should try to work in some unicorn startup in hopes of getting rich?
Rich is where your money makes you enough money to a point where you need not work to maintain your lifestyle (but can choose to).
> Lacking sufficient money to live at a standard considered comfortable or normal in a society.
Said no one ever. That's almost insulting to people who have actual financial problems.
Poor? Really? We make a great living, none of us are poor. We are very well off and you don't need a winning lotto ticket to grow your wealth outside of your salary.
