I had the same thought you did. I don't want to get into stereotypes or tropes but generally speaking, the work ethic in SE Asian countries is at least equal to, but likely tops, that in America and blows away those in Europe.
There's always been a subset of America that seems to envy European countries because they get more vacation. What gets left out is Europe is suffering from slow growth, weak productivity and demographic issues. Europe is falling further behind the U.S. and China economically.
So it's easy for us to say we should be more like Europe but how many of these same people are going to be happy when our living standards decrease?
There are always trade offs and I'm not suggesting people in America should work themselves to death (or everyone should work 80+ hour weeks like some do). But notice how we love to celebrate when the stock market goes up? It's not going up because investors think American productivity is going to drop and growth in America is going to slow in the future. Are we willing to see that growth slow in the name of a "more balanced" life?
