After a success under your belt, it's easy to keep going and get more funding. There's no shortage of capital looking for people to fund right now (it goes through spells).
The first time I got funded, it was through a rich elite idiot's social connections (CEO). CEO was a sleazeball, and got all the financial and most of the branding benefit of the venture, despite doing no work. I launched a successful business with CEO as the figurehead, and in the process, I got:
1) Connections and network
2) Visibility and branding
3) Stepping through the process once. Moonlighting can be enough time if you're efficient (which you can't be if you're muddling through figuring stuff out)
It was a stepping stone towards financial stability, and I'm much closer. Socioeconomic mobility is a process. Some people get lucky, of course, but for the most part, there's a pathway from:
1) Unskilled labor; to
2) Professional labor loaded with student loan/mortgage debt; to
3) Financial stability; to
4) Being able to launch high-risk high-reward ventures
That's possible, but it generally takes a few generations:
* It's possible for someone without an education to send kids off to college through public schools, but they'll have a hard time competing with kids who were exposed to advanced tutoring, math, STEM, makerspaces, etc. from an early age (children of professionals)
* It's possible for first-generation professionals to network into power networks and achieve financial stability, but they won't be in a place to quit a job and launch a new venture.
* And it's possible for children of professionals to then (finally) engage in a few high-risk high-reward projects until one pays off....
