If the pessimism in this thread bothers you, imagine how much your woefully out of touch survivorship bias and bothers everyone else in this thread?
One of the top comments that responds to your post tells you that the math changed. This is true. The fact that neither you nor Garry talk about the concrete specifics of this means that you're either unaware of it, or worse, intentionally sweeping over it.
You really think that what is "actively training our young people to avoid taking risks" is all the "negative takes" on startups? What about the changed exit environment where companies are staying private longer and equity shares are no longer outcompeting public company compensation? Poor or inexistant options for liquidating large holdings of early company equity? Liquidation preferences, dilutions, and founder enrichment allowing grey-hat founders to self-enrich at the expense of their employees? How about the increased ability of large companies to compete with startups and turn their products into mere features? Ballooning student loan debt, rampant social inequality, a collapsing middle class labor market and automation?
You know what I think is actually happening, based on the interviews I've given working at various startups where we lose great candidates to more established companies? I think candidates are getting smarter. If they're smart enough to make outsized impacts at startups, they're smart enough to make outsized impacts at large corporations and make sure they get commensurate compensation. They know that they have better access to a tried and true organizational structure around the software development and revenue line development lifecycle.
A lot of this completely changes if you're the founder. That's probably the one perspective where the ownership structure is so radically different and more advantageous that it's very much worth it over being a mid level manager or executive doing the same thing at a larger company, if you can pull it off. But if you're not a founder at a company any earlier than late series B or C, you're generally taking a proportional risk for a much less proportional reward if you join as an employee -- not just financially, but organizationally and directionally (in career trajectory).
And, if there's one thing I can't stand more than anything, it's when founders wear rose-colored goggles and can't admit this truth. Not implying you're doing this, but I'd advise anyone in danger of this to never drink the kool-aid you sell to the point where your reality-distortion field obscures your inability to see the very real reasons why people make (and remain happy with) these decisions, just because it threatens your life choices and identity.
