I’m in Japan right now and they are fixing their issue by a weak yen. They are bringing in a ton of foreign money due to the weak yen and the high productivity. They didn’t fall victim to the covid pay to stay home game. They still work like they did pre-covid. So they had no drop off in productivity as the USA did.
Honestly I think the USA would go bankrupt before Japan does...they still work over here.
I was very impressed how fast they repaired damage to roads & buildings from that powerful tsunami. Japan is amazing country.
