there's a lot of strategy and also a careful effort to stay on the right side of the law (albeit with the occassional change of law if need be).

it's not impulsive at all. they're trying to make the most money while still playing by the rules.
just like football players try to score the most points while playing by the rules.

it's up to the referees and regulators to set and enforce the rules so that the game yields good results for all rather than just mayhem or biggest guy wins.

THAT's the problem.
