I don't see how it's such a hard concept for so many to understand and the OP should read the whole post that is about to follow...
Reagan raised taxes on all but the wealthiest and even then their cut their was very meager considering all the tariffs and excise taxes they had to pay plus the fact that their payroll taxes reduced their income and increased their expenses. Reagan also taxed the poor to spend on the rich and on inefficient govt bureaucrats... he was a Hamiltonian Conservative to the core, at least after his VP had him shot.
As for the CG taxes, they probably only keep the wealthy ahead. Enough people need to realize that the deficit is an illusion and that there is no such as fair taxation... that's why we need more exemptions and deductions and even credits as long as they don't give people more than they would've had with no taxes.
If the govt tries to take everything after $100k, they won't get it. If the govt tries to take 100% of the first $5K, then they won't get it. Why do people even try to analyze the math behind it? Trying to analyze everything mathematically doesn't work... it only half works. It's just like trying to apply biology to everything... it won't work because it only half works. It's just like trying to use a calculator. Calculators can't be brighter than humanity because they were created by the brightest men and meant for any man.
All of that said, I think that too many people are worried about the deficit (which causes people to want to be taxed how they want to) and not the real issue which is the govt spending money that it doesn't have of right.
Dr. Paul's Restore America Plan was the best thing the little people had going for them, but a bunch of poor but very pro-business Republican voters wouldn't support the man with the good plan. I bet 2/3 of more of the big fat Republican business owners out there suck because they don't know how to work around the govt... liberal firm directors are a lot better than Republicans but liberals both classical and modern are in the minority unfortunately although many conservatives are progressives and vice versa and Republicans are Keynesians are from hell... they care about "growth", about deficits, about country over individual happiness, and about unemployment but not what matters. As for myself... I don't work against the govt that well, so I know to know my role which is to never in my life be a leader and to never in my life be a blind follower.
Also, Gingrich's "reformist" FlatTax plan sucked @$$, but it makes me angry how it was ridiculed for what it probably wouldn't have done (that is, "blowing holes through the deficit").
Why do people reject half or more of what the Austrians say? Why do so many people think Milton Friedman knew what he was doing? He endorsed competing currencies when he was like 90 or 92 years old (probably because he felt so bullied about it) but then he probably didn't even realize they wouldn't last in a republican national state... if you'll remember, Jefferson tried them (when he repealed the statist silver standard act to put the breaks on FBUS) and then Madison started a war and started another banking and monetary cartel less than 10 years later. Madison was quite possibly the dumbest, most aristocratic President ever and what he did to Jefferson was evil and sick... Jefferson was so sweet that he even named at least two of his kids after that asshole FFS.
