Ok, rephrase that as "at least I'm only losing 80% of my salary instead of 100%". Plenty of people who could create great things are also saddled with families

Ok, rephrase that as "at least I'm only losing 80% of my salary instead of 100%". Plenty of people who could create great things are also saddled with families and expenses that run to 80+% of their disposable incomes. It's all well and good to suggest that an individual can live on ramen noodles, but a family and young children cannot and should not have to. That leaves only a few options left for such people to start a company: do it on the side in evenings/weekends; and save up a nest egg then quit/reduce your job to work on the startup. Suggesting that willingness to forgo having a family is a pre-requisite for entrepreneurship is fallacious.
