The trick, if the players wanted to rig the game and had knowledge of the total prize pool at the start, would be for them to secretly meet up beforehand and place a stake with an outside agency with legal financial responsibility.  They'd place an equal share of that stake with the agent and then when the final totals were revealed the agent would give the stake back but only if everyone acted ethically.  That system would turn everyone against the house.<br><br>I had an interesting thought.  I'm not sure what the policy is in every country, but I know some countries have public income tax systems where everyone can just look up what other people's income and taxes were.  In the U.S. we don't.  We couldn't even get Trump, who promised to disclose his taxes, to disclose his taxes.  From the countries I'm remembering I think in general the countries with more transparent tax systems also have stronger social safety nets.
