Sorry. I did write it a little quick. But the argument about US companies thinking short term and Japan's companies thinking long term has not shown that Japan has performed better than the US. Their economy has been in a tailspin and is barely surviving. So the criticism about thinking short term is a wrong belief.
And for the second part, companies tried to do what was suggested and offer options, worker flexibility, worker happiness but they didn't do much better and they even did worse than the traditional beliefs, so except for a few cases it really isn't being tried any more.
