Earlier quoted context omitted.
Sorry, tragedies of the commons don't have individual solutions. If everyone else is overfishing the common supply, you overfish as well, or go out of business. If everyone else is using performance enhancing drugs, you use them as well, or drop out. If everyone else is working 80 hour weeks and thus bidding up the price of houses, you do the same, or you can't buy a house. These things are very well studied in game…
Is this issue really a tragedy of the commons though? What resource is being depleted?
Also see the book "Two-Income Trap", it basically describes how households didn't become better off from making both partners work, because that just bid down the price of labor relative to housing and education. Everyone ended up in the same position as before, but now they work 2x more and cannot opt out. Also the non-working partner in the family provided a safety net because they could start working if things got rough, and now that safety net is gone.
