How tough is life when money is tight ?

I feel so bad that I don't understand money and the elite life that many people live. Like I can't even imagine how life would be if you make $100k like that's a pretty decent salary for most people but I guess every state or city living costs are different and for some $100k is nothing to them. Maybe the way they live their life from having a nice vehicle to owning a house and other things. But it feels so bad when your constantly low on money and working a regular job feels brutal. Your being overworked and feels many times underpaid. Life just remains stegnant and day by day living costs goes up from rents to auto insurance and health and so forth. I can't even believe I had to get rid of health insurance simply because it was just too expensive. And I also feel guilty that Im throwing my money in a drain every month by renting. Even when many people have suggested to buy a small house or something that can be your own property. I also feel like going to college because minimum wage jobs just ain't doing it enough. People working night shifts to 6 days a week and top of that side hustles to make a living.
