I strongly agree with this. A lot of people are happy in college and they're almost all living on less than $24k a year despite working over 40h a week (although schoolwork is a lot more engaging than industry IMHO).
That's because it's expected, all their friends are living in the same way, and they see this as temporary, with a larger income not that far off. I can say I was very happy with minimal income in my university years, but would not be anymore as my friends are out of the campus and getting forward with their lives.
This is what causes people in the West who earn $35k and $350k alike to feel 'poor' despite the fact that even the former income is already in the global 99th percentile.
