First, I don't really have a "cause" here, I was just addressing Randy's assertion that only the rich should pay taxes... it's pretty much the case already.That's largely the case already. The top 50% pay 97.11% of all income taxes. The top 1% of earners pay 40.42%. Before long we will have a voting majority with no income tax burden. [link]
Pointing that out certainly doesn't help your cause.
Indeed, the top 1% in the US earns 20% of all the income. In other words, 99% of the population gets to fight over the remaining 80% of the income that's left. The bottom 50% earn only 12.8% of all income in the US. So, yeah, I would think the half of the population that fights over less than 15% of all wages in this country shouldn't be paying taxes. Good Lord.
If you look at wealth rather than income distribution, the picture is slanted even more toward the top end.

However, your assertion that an overwhelming majority "fights over less than 15% of all wages" is absurd. Capitalism is not a zero-sum game. There is no fixed pie that people compete for. Surely the concept of wealth creation is not completely foreign to you.
