Japanese leaders get free houses, air travel, etc. worth millions. In the US you must report that to the IRS, but not in Japan.
However, American leaders scam their company using buybacks, which is the top white-collar crime of the past 2 centuries. (By boosting EPS, your options/shares are worth much more, and you can automatically hit any EPS targets.)
Even hardware engineers in Japan are treated really well - the company will find you an apartment, a wife, etc. When you travel, you don't carry anything, you can Fedex it ahead of your trip. Your business card from a major company is essentially a VIP pass everywhere.
