He was consistently right during the Great Financial Crisis. That the "grownups" who cut their teeth in the 70s, a supply side recession, were applying the wrong lessons to the GFC, a demand side recession. Europe kept trying and failing to austerity its way to growth. The Republicans shrieked the same, and cost us a perfect opportunity to improve infrastructure basically "for free" as investors paid for safety, i.e. borrowing money was free (recall that in Switzerland rates not only went zero but negative).

Also that the euro is a straitjacket: tying together monetary policy in the absence of shared responsibility is a bad thing. Germany didn't want to bail out profligate Greece, Portugal, etc. Meanwhile it had benefited from the euro being weaker than it would have been without them (making German exports more attractive). In fact, shades of today (with respect to the tariff circus): Germany said, basically, "well everyone should be responsible enough to have a trade surplus", which is of course mathematically impossible because, and this is another one that stuck with me, my spending is your income and your spending is my income.
