I have an objectively higher QoL than almost anyone in the EU or Japan who wasn't born rich.

After many years as a SWE without a college degree, I was able to buy a large 5 new 5 bedroom house within ~25 minutes of my employer in a beautiful city, I have a full time nanny for my children, a luxury car, padded retirement, and plenty of other money to buy what I want.

Where else can a smart, hardworking person achieve that who didn't come from generational wealth?

I'm not so unique either, I have some friends I've known who similarly didn't come from money and have been able to build up careers that support a wonderful lifestyle.
