Republicans absolutely, unequivocally, believe in class. Better people have more money. Period. They can buy better products with that money - otherwise there's no point in being wealthier than others. Democrats are kinda sorta sometimes maybe occasionally OK with this but then abruptly not OK when the political winds change a bit. The party of ambiguous ethics are the Democrats. The aristocrats' party is the Republicans.
Directly asked, both party types lie. But if you look at a few dozen policy positions an individual policians has, with emphasis on the less conventional (the ones with ready talking points) ones, it's really easy to triangulate their positions and contradictions - for a political scientist.
edit: Let me be even more detailed. I had to have my accountant rework my taxes 3 times. Once because of a retroactive law change after the end of the tax year. Once because of the inconsistency I discovered in official documents. And once because ETrade's documents and my employer's conflicted. Both of the latter were prepared by professionals. That's pretty typical of my filings. If it's so complex that all of that is fairly routine, that IS the government's problem. I have no problem keeping track of my own records; in fact my own record keeping and fastidiousness led to the discovery of all 3 of those problems.
Does that mean it might be safer to be less fastidious so that no-one can uncover records that never existed?
