That is just such a defeatist attitude. It reminds me of the classic Gen X complaint when I was growing up (we're the first generation to have a lower living standard and worse job prospects than our parents) but we didn't just give up. I'm regular folk. I waited tables and drove taxis for years and coded in my spare time. I started somewhere between 5 to 10 failed companies depending on what counts as a "company".
The one thing I learned when I was young was never buy anything on credit. I was up to about $20k of debt when I dropped out of college. I cut up my credit card and I paid it off and did not buy anything on credit again until my late 30s when I bought a house and the first car I ever owned that I didn't pay cash for (which I quickly paid off).
There were long periods in my life where I lived on staple foods like rice, worked 12-16 hours a day, and spent half my income on rent. I also spent 12 years backpacking when I got myself into a situation where I could write software remotely, and I realized that This is completely normal in the world. Living within your means is normal. Living hand to mouth and saving a little is normal. No one had it as good as the boomers in America, ever. No one will again. Being able to buy anything on credit is a wild abberation that cannot last. But I live like my grandparents. Frugally.
I've only ever owned 2 pairs of shoes, 4 pairs of jeans, 8 shirts and 8 pairs of underwear. I replace them when they wear out. I also own a house now, mostly paid off, and have about half a million dollars in the bank. Does that make me rich? I don't feel like it. Every day I go out of my way to earn and save instead of spending.
Make money and save it. Don't buy shit you don't need. Don't rent anything you don't have to, and don't fall for the credit trap. When you buy things, fix them instead of replacing them. Don't sell anything.
And don't look at what other people have and wish it was yours. I'm not religious, but there's a reason that covetousness and sloth are cousins in the list of ways you can ruin your own soul.
If you refuse to use credit, and you live well under whatever your income is, you will be able to afford things of value once you pay off the mistake of taking on debt in the first place.
