Also realize that the income structure of a country like Japan is NOTHING like that of the US, specifically as regards CEO/VP compensation etc., so all salaries will be lowered accordingly as well. Miyamoto and Kojima no doubt earn beaucoup bucks, perhaps on the order of $500-750K, but if it were an American company doing the same volume of business, they'd likely make $3M+.
For comparison's sake, the average CEO in Japan (across publicly-traded corporations) earns roughly $400K or so, while the average American CEO earns
$11M (1999 data; the disparity has only increased since then). Accordingly, the entire wage structure of companies and their employees is shifted downward for Japanese and other foreign companies relative to US companies (except, of course, for those at the bottom, where nearly every other industrialized nation's "minimum wage" and average worker compensation absolutely dwarfs ours-- go figure). Thus ends my Gaming Forum editorializing for the day <Loki scurries back to OT>
EDIT: The average US CEO earns roughly
490 times as much as the average worker in their company, while in Japan, they "only" earn
20-25 times as much; in Britain, it's "only"
35 times as much. Something to chew on.
