I had a ton of fun in my PhD. It probably wasn’t the best route if I was trying to maximize total lifetime earnings, but I’m happy with the route I took.
In fact I liked it enough that I often joke that my retirement plan will be to get into another PhD program for the stipend/insurance and just do projects to help some junior prof get their career going
I agree that it can be fun. I also devised a retirement plan as a graduate student, figuring out what sum of money I would need to live the rest of my life living the graduate student lifestyle without the hassle of being enrolled. Less than a decade after finishing my PhD I was able to walk away from my career into that lifestyle. Certainly not for everyone, but if it floats your boat, it is certainly an achievable plan.

Imagine being a young ambitious student not getting placed into a PhD program because some old dude doing it for the benefits and the lolz took the spot.
