I love all this speak of class warfare (class conflict) however it is inherent in capitalist systems. Its the nature of the beast I am not saying its good or bad I am just saying it part of capitalism. If you don't believe me read some Marx, Das Capital has a great analysis of class conflict and the nature of capitalism.
As for taxes no matter how you divvy them up someone will always say they are not getting treated fairly. The rich and the large corporations get tax breaks because they fund the campaigns of politicians who set the tax codes. Its as simple as that and as long as there is money flying around people will become corrupt its just what happens.
