Contradict yourself in the very next few sentences brehs.Yes by income. I'm over $125k in a supposedly "low cost" state GA. Having said that I don't think being middle class or even upper middle class is all it's cracked up to be. Sure it's obviously better than being lower class. Having said that middle class and upper middle class are still pretty much in the same bind as lower class folks. They still have to work everyday to maintain their life style. It's not like I could stop earning an income today and be ok. It just mean I can live in a nice area and drive a nice car, blah, blah. And they probably have enough in savings/investments/etc to last them a year or two unlike the lower class. At least some middle class folks do others don't.
In my opinion you need to be rich(not super rich). But if you make 2 or 3 million a year then that is game changing because you could probably live comfortably off the interest for the rest of your life. Then you could easily invest 100k in say a rental property without the overwhelming stress of it not working out. This is where I'm trying to get to. Only then will I feel like I "made it".
