> low and middle income jobs, such as teachers and firefighters or nannies and cooks, are key to the local economy.
Someone else commented in this thread how all these jobs (meaning every non-tech, middle-class job) will begin to pay more once they're more in demand. The assumption is that programming/tech is highly paid because it's so in demand, and every other job isn't because vice versa.
Let's just take one job that is critical for a local economy - teachers. Some might mention that because of online learning places like Udemy, teachers for middle or high school education could be gotten rid of without too much harm. Even if you think that's true, consider children ages 0-12. Those children, undoubtedly, still need teachers/daycare of some kind. They're simply too young and at this point most adults prefer not to deal with kids, pursuing their careers instead (this is good! More brains in the knowledge economy helps spur innovation).
However, San Francisco is currently experiencing a teacher shortage of several years [1], so that vice versa I mentioned above is simply not true. The city is offering cash bonuses for teachers now, and it introduced some legislature to attempt to incrementally increase their wage, but it's not enough. Fewer people are entering the profession, knowing they need more than a cash bonus but a continually valued job that gets them consistent revenue to be able to afford to buy a house here. Even those that might have been attracted to teaching, they figure - well, I need more money to live than what being a teacher pays. That's simply an unacceptable standard of living for me and my future children.
So yes, those potential teachers can instead come to your non-profit and those individuals will be able to afford to live, fairly comfortably, as full-stack engineers.
But the community as a whole will have an even more drastic lack of teachers. While non-profits like yours help a few individuals, it is certainly not the panacea HN purports it to be.
