And that's certainly the way the younger generations see it - so why not do your own thing? (Hey, I agree)
But given that most businesses require more work and eventually fail, taking a job is still much more secure. Perhaps this will change in the coming years, but not yet.
About 55% of startups fail within five years. Ok, so there's obviously some risk in starting a company.
How likely is a 22-year-old to find a job, even at a stable company, where there's a 45% or better chance that it's still worth going to work in 5 years? Not very. Most people get pigeonholed or down-tracked; not everyone can be "protege".
I'm 25 and on my fourth "career". I recognize that no single effort or job is going to deliver better than a 50% chance of liberation and success, but I have a hell of a lot of chances, and I've learned a lot and made great friends in each of my three cycles. I don't fear losing a job-- done that, bounced back-- but stagnation is terrifying.
