That's not a criticism of corporations, just pointing out that taking a risk and striking out on your own isn't necessarily a reckless decision.
And I don't think startups are reckless, but I think a lot of the people that join them fail to do rudimentary financial calculations as to whether doing so has a better expected return than a safe(tm) job.
Otherwise, they wouldn't accept chicken scratchings worth of lottery tickets and 20-50% lower compensation. But yet they do, over and over, no matter how many people lay it out how bad an idea this usually is.

So, basically, your point is that you should sneakily hide your best ideas from your employers and then strike out on your own when you hit that magical amazing idea! You know, that idea that is obviously going to be an amazing success and you can know that ahead of time! People that foolishly try to succeed on their own time are rubes! Instead of accepting a check from the government, you should mail it in with a job you're entirely checked out of until you find the magical secret sauce to make yourself a billionaire. That's great for everyone right?
To some extent, but big companies are likely to be much more conservative towards new ideas. If they weren't, there would be little benefit to being an entrepreneur.
IMO the benefit to being an entrepreneur is that if you truly have a winning idea, you can own a lot more of its fruits by pursuing it from your own business. For it requires nearly the same skillset to procure VC as it does to persuade a large company to let you build something. Risk is and should be proportional to return.
To that end, I have nearly 20 patents filed from within large companies, most of them single inventor. And my salary amortized over a 4-year startup life cycle is on par with what I would have gotten as a non 3-letter title at an acquired startup that wasn't a Google or a Facebook.
So why take a chance on failure without the chance of a big payout? And except for the 3-letter titles, that's what a lot of newbies unknowingly sign up to do, risk >>>> return. I have no desire to socialize this learning experience for them.
It kind of is though. The cost of making failure painful is all the potential innovators who decide to get a safe job instead.
