Instead of anti-trust laws* that are enforced some decades, not others, I'd rather just see market share affect tax rates. Maybe for every 1% of the market you control, we add another .1% to your rate? Not really sure what the right equation is, and measuring market share would be contentious... The current system isn't without its problems though. * UPDATE: Well, collusion would have to still be illegal, this doesn't really cover everything.
