Once we asked if club activity were mandatory at the local school. We specifically asked about the mandatory aspect. The answer was "everybody does it".

Now: nearly all corporations pay dividends at about 30% of profits as policy.
Japan may not be reactive or proactive, but it does voluntary unity pretty well.
But was this a short-term gimmick to encourage investment? Did it work? My understanding is that high dividend payout represent weak reinvestment and overall lower growth.
