Earlier quoted context omitted.
While we might be able to justify one person paying orders of magnitude more taxes than another, based on the overall benefit to society as a whole, let's not pervert language by describing that system as 'fair'. In fair systems, people get the same service for the same price.
Yeah, and in an anarchic system, power and money flow upwards until it's unsustainable and it collapses. We're not living in caves, definitions of fair should include upward mobility. And who says they're not getting the same service? Wealthy corporations and individuals get a ton of services from the US gov't, from subsidies to infrastructure to direct benefit from the State Dept and military.
Are we talking absolute upward mobility, or relative upward mobility? If absolute, then we already have that. If relative, that's impossible...not everyone can be simultaneously relatively upwardly mobile :)
