Earlier quoted context omitted.
What technology worker spends all day worrying about survival? It's not hard to save up a couple years living expenses on a software engineer salary, and it's not hard to find another job (or even found a successful company) if you have a couple years to do it.
With or without kids + family? I don't worry about those things, but 'it's not hard to save up a couple years living expenses' depends a lot on your ... dependents.
Whether you will do this depends a lot on your priorities. Some people want to get their kids the best toys, clothes, and vacations that money will buy. Others would rather give them the gift of parents that are not totally stressed out and have time to make it to their soccer games. There's not a right answer to this, but as someone whose family's household income hovered around the $50K mark for most of my childhood, I can say that you don't really suffer from not being able to afford a trip to Europe every summer.
