The funny thing about international economics is that it really depends what metric you chose, to prove that it's "Strong," or whatever. It's really easy to borrow $Trillions, then balance the federal budget. It looks good when you point to that for the voters, but the bill always comes due, with interest.
At some point, we have to stop saddling the next generation with our fuckups. Millennials are already incapable of paying off their debts, and buying their own homes, working 2 jobs (If they can get them, with no experience, and all the competition) at a Minimum Wage that's been fixed since before they're born, after the housing market, and the tech markets were exploited to back-to-back crashes.
But I'm sure it's a great comfort that the economy is "strong." Now, if they could just have families, and provide for them, the way the Boomers claim to have, back in their day.
