@Cycloptichorn,
Cyclops, you use cookie cutter liberal cut and paste. If all of that were true, it would translate to what we experience, don't you think? I can tell you that most of our friends all started out in very humble beginnings, with not much money. However, all of these people are prime examples of being responsible, whether they went to college and got a degree or not, they all have worked hard, and all live comfortably with decent lifestyle, savings, and a retirement waiting in the wings. And none of them worry about other people having more money, as you apparently do. And count me as one of the group that had little money growing up. I earned every dime that it took to go to college, then got a decent job as a professional, then later became self employed and a business owner, successful by the way, which is more than can be said for our president that has done nothing of note before getting into politics.
To summarize, I think post Reagan has been a great time in our nation's history when the poor can get ahead, if they applied themselves. The contrary is true if they expected the government to take care of them and did not work very hard to better themselves and be responsible in the process. So I do not see any evidence of your statistics being realistic in real life, at least not in my experience and the hundreds of people that I know and have known.
By the way, I would guess that the upper 1% or 5% of the income people pay a higher percentage of the tax revenues now than they did prior to Reagan. Can you refute that? Also, has it ever occurred to you that rich vs poor might be a function of cultural problems, more than it is individual tax rate structures? Or perhaps it is a function of Democrat policies, such as over regulation, corporate tax rates, and union bullying, driving manufacturing offshore?
