Because this is 'Murica, the land where logic, reason, decency, and compassion go to die. We’ll spare no expense to save money then write it all of as the cost of doing business. Fixing the problem isn’t nearly so attractive as just criminalizing anyone that isn’t helping our corporate overlords to turn a profit.

“Oh beautiful for smoggy skies, insecticides grain And strip mined mountain’s majesty, above the asphalt plain America, America Man sheds his waste on thee And hides the pines with billboard signs From sea to oily sea” – George Carlin
