More supply often helps that problem too. It's easier to engage in price-fixing when there are only a few items of supply that are controlled by only a few. Once there are more options, it's much harder to obtain or maintain monopoly control. It's also much harder to hide illegal price-fixing schemes when you need to have tens of thousands of co-conspirators.
