What Todd is saying if the indians have not been paying taxes, then the tax on them should be a tax reduction for everyone else. But the guvahnator needs tax revenue, so the people didn't get that cut. So, in reality, the people got their taxes raised, because if the tax were to spread taxes out evenly, everyone else should have got a tax cut. So in a way, you are right, there is some equality here, everyone got their taxes raised.
In the end, I think they will pass it on to the consumer, like any other business. So not only did the people not get the tax cut they should have got, they will pay more out of pocket at the casino.
A tax is never good.
