I beg to differ. Shortly after the country was born, politicians discovered voters would sell their votes cheaply. That's when we, the voters, started to cede our responsibilities, to grow government into a controlling entity. It all started in the first few years when the USA a was little more than a loose confederation of states. Long before the "gold standard" was discarded, which was also something the people wanted as it would make more moneys available.
The "American Civil War" cemented the idea of a strong, centralized, omnipotent government. Then the people started enjoy government subsidized railroads, later airlines, interstate highways and the like, even as they created the "professional politician" so roundly decried today. So, over the last couple of hundred years one generation after another sold their birth rights for the convenience of laws and regulations which were to make our lives safer and easier. In some cases this was true but the piper must be paid through increased regulation which is always followed with increased taxes to pay for construction and enforcement of the new regulations the public clamors for.
To blame political parties for the state of the nation is absurd. Politicians only get elected when they can get sufficient numbers of voters to vote for them. So, money has to go out from Washington, state capitals and municipalities to the voters. Roads must be built, sicknesses cured or eradicated, children educated, wars fought, large soft drinks banned, increased MPG, wet lands protected, personal communications intercepted and read, day care regulated, farmers subsidized, various animals and insects must be protected, armies raised and maintained, employment for everyone, unemployment insurance for everyone. The voters want many things, new things are discovered almost daily and the politicians must respond in order to get elected and deliver.
The people want what they want and they want it now! A lot of what we want isn't, in the long run, good for us.
