It feels like a semi-predictable outburst of the-need-for-joy following the dour years of Covid lockdowns and travel restrictions and general down-sentiment; a society-wide emotional pressure relief valve.
I can't see it playing out as any kind of long-term pattern because it's unsustainable, but having said that, there are 300 million Americans with different scales of tolerance, and so the relief valve could be steaming along for quite some time. The sustainability being how willing people are to work longer in life to pay off their debts.
What happens when an increasing number of people die with debts? Is this a likely scenario?
