It's hard to recognize privilege when you have it.
If you happen to have rich parents who pay for the best college, that's an awesome opportunity. Nobody should have to feel bad about taking it!
If you are poor, but happen to have a lot of spare time, that's also an opportunity.
Complaining about privilege is not actionable. Focussing on opportunities is a lot more constructive: We can look for ways to give someone an opportunity!
It is actionable though. People can make hiring decisions on a candidates work rather than what they do in the spare time, just as they do in every other industry besides tech.

You don't need to be young to code profesionally nor you need free time. Good job allows you to learn on the job. You need eyes and hands.
And no I didn't have a lot of free time. I was working and going to school but when you're young you frankly don't need a whole lot of sleep.
