If you're a NEET, you have more time to looksmax. Looks are basically everything, and if you're NEET, you have free time to go to hobby groups, go to classes at the gym to meet women, run daygame/nightgame, use Tinder, and even interact with a social circle with an odd schedule. Now, of course, this is assuming you're financially stable, either collecting NEETbux or leeching off your parents.
People will say "you need a job and your own place", BS. Girls don't care about that, they care about looks. Also important to note I'm not stating being NEET will give you a high chance of ascesion, but just a better chance than a wageslave job. 40 hours a week of working plus commuting takes up a lot of time and energy. NEETs are spared that and have better chance to get their dick wet.
