That's a great illustration as to why inequality matters, not just poverty.
I'm not sure what inequality has to do with it. To me, it sounds more like chasing the joneses. There are plenty of free activities.
What you call "chasing the joneses" is perfectly expected human behavior. People compare themselves to their current metaphorical neighborhood in time and space (not to their grandparents or to hunter-gatherers) and they make their life decisions based on that: college, career, having children. It's just nonsense to dismiss it as "hey, that's jealousy" at a population level.
