That doesn’t need to be negative (okay, the no food/no money thing is bad). And I’m not saying it’s the perfect life-style. Living like that will eventually become unhealthy long term. But there are scenarios where it’s okay. And if it’s just a phase as a means to be able to transition into a better situation, rather than rotting away inside by being a “functioning” worker bee who lives by what “the society” sees as the way you should live your life. Quitting a dead-end job, not going out socializing with people you don’t really care about, just not being who everybody expects you to be, is okay. If doing those things just makes you feel miserable and empty then that’s how you’re wasting your life.
Balance is important and knowing what you want and what you need.
edit: as important as that balance is, as quick a neet can turn into a hikikomori (which definitely isn’t a good thing). If someone wants to stay at home it should be their own choice, not forced by any circumstances.
