So, lets cut the BS here. He's never compared himself to those people. It is obvious, he's talking to the vast majority of other people in "safe,rich areas", who also don't have sick parents, disabilities, etc.
And who also have no reason to start families until they are settled in. That's a choice, had you not heard? And if you choose to do it early in life then, again, it's a choice, so, hope it was the right one for you. If not, plenty of time to not become a cog.
He's not the only one, he's not a hero, and he's not claiming to be. But there are a lot of people out there telling us the joys and genius of the 2.4 kids and the job at Google with fancy cars and vacations. We need more people talking about the joys of charting your own path. Less people need to feel like they are 'wrong' for not following the comfortable route, and more voices are needed.
