Easy: it's deliberate. Although they would like us all to think that they only mean well, that they are just so embroiled in the day to day that they don't realize how it all adds up, the truth is they know exactly what they're doing.
Not one of these societal leeches has the guts to stand up and say "Hey, we don't need to pass any more laws, we don't need to regulate things even more, what we need to do is go back through this bloated mess of laws, weed out the ones that aren't needed , and make sure we are enforcing the ones that are, with a view to staying within the defined powers of the Constitution, so that our people can enjoy the blessing of liberty without the overbearing presence of the government breathing down their necks at every turn." Not one politician in a million would have the cajones to stand up and say that, because it would be political suicide. Just because something is political suicide doesn't meant that it's not the right thing to do.
