I hope it’s not off topic but it seems to show that one person businesses are probably not the way to go for most people- you will have a much more predictable income in a larger organisation and on average you will be better off financially too. Anyone telling you otherwise is probably a VC trying to make you work for them (or fail competing against them)
Nobody is arguing with it, however if I had to choose between 100K in corporate world and 80K running on my own, I'd go with latter no questions asked.
