There are a few weaknesses in your argument. Just as the Preamble talks about a "more perfect union," human nature has been being refined over the same period.
Slavery was inherited from the various colonial powers, primarily the English and the French, and individuals, both great and small, worked to end the practice as early as the start of the country, while even those who held slaves understood their own hypocrisy, such as Washington and Jefferson. Likewise, the repression and attempted extermination of the Native population had as much (if not more) to do with the greed of the electorate as that of the elected. Ironically, the original colonists thought the Native Americans were white men simply made ruddy from their exposure to the sun. I would also point out that the Natives played as much politics and silly buggers with the colonists, at least initially, as did the colonists with the Natives. The use of the Connecticut colonies as a buffer between the more aggressive Pequots and the weaker tribal nations further east by said weaker nations was just as mischievous as what the settlers did to the Natives or each other, early on. Likewise, the level of settlers friendship with the natives tended to be inversely related to the amount of gold they had.

People forget that the Native Americans had slavery, war and genocide long before the Europeans turned the North American continent into the religious equivalent of Australia. The Pequots, for example, wax poetic about "returning the land" land to the tribes that lived there before European settlers arrived, but look sheepish when you inquire how they came to live in such lands... by Pequot oral tradition, they more or less took the lands militarily, culturally obliterating the original inhabitants. Human nature is human nature, regardless of the color of one's skin. The fortunes of the African kingdom nation of Dahomey, for example, rose and fell based on the slave trade. Likewise, if you have ever seen the factor's stations in Africa, you would know that they could not have withstood the ire of the native populace, were that at least some of the tribes not fully complicit with the slave trade.

Generation X has been holding things together with duct tape and bailing wire for so long, while fully expecting to up in a puff of atomic smoke.

In what way, pray tell, are payday loans "evil?" There is no malicious intent on the part of the lender, nor do they force you to take out a loan. There is naught but greed, which is more or less amoral in nature. As for dealing with the Saudis, I would point out that most of the folks most in need of "green energy solutions" to deal with the transitions away from petrochemicals are not, shall we say, on the happy list of Amnesty International. Stupidity readily covers his willingness to do a deal with the Saudis and then run for governor.

"Too much democracy" = mob rule.

In a truly "democratic" system, the majority rules, period. In a republic, there are protections, at least in theory. People don't know their rights anymore, mainly because we replaced civics with "social studies."

People think voting is a right. It isn't, it is a responsibility / duty.
