[Repeal The 17th]

I look at it this way:
You can’t beat the house.
If you could beat the house, there would be no house.

I look at it this way: You can’t beat the house. If you could beat the house, there would be no house.

The house doesn't have to beat everyone. It only has to beat the majority of the gamblers who show up, as measured by dollars won vs dollars lost. The winners provide free marketing by talking up their wins to people who would lose even if the odds favored them.
