The rich already pay more, significantly more than their fair share. If the guy making $50K had to pay for his fair share of the local, state and Federal government services, he would not be able to buy a cheeseburger. Infrastructure ain't cheap. We all drive on the same roads and have the same emergency services.
The cost to fight a fire in a $200K house is more than in a $10M house that has a fire suppression system, alarm system, etc., but the guy with the $10M house is paying 30 to 40 times on the property tax.
These little facts that get lost in the rhetoric...
