The Constitution gave us a good start, with its definotion of trim federal gov't having fixed, yet ultimate powers, many rights reserved to the citizens directly and leaving all else up to the states to decide. That all collapsed, or at least started to radically shift, upon passage of the 16th amendment, cited recently as allowing PPACA and other unfunded federal mandates.
As liberals (leftists) gained power the Constitution shrank in meaning, allowing the "importance" (popularity?) of a matter to make it into a new fedral power (e.g. edication and income redistribution). The gov't, mainly federal, has grown ever more powerful and, of course, expensive to maintain.
What used to be small and provide only needed common services is now evolved into a huge nanny state supporting some from cradle to grave while taxing others to keep that nonsense growing. Federal political office now requires up to a $1 billion in campaign spending to attain. A small elite group of rich, mainly lawyers, pretend to run the nation, but are naturally beholden to those that allow them to spend more than 1000x what a term in office pays to "apply for" that job. Public servants have become the public's masters, forcing we the sheeple to pay them handsomely and worship their wishes that are foisted upon us as laws.
The govt is permitted to run up massive debt in our names and then explain, to us, that they are powerless to stop the spending madness, lest they must force suffering upon us. We, of course, meekly believe them for fear that we may lose some promissed future (or current) benefit if we cross them. We formed the nation based (partly) on objecting to taxation without representation yet now accept representation without taxation as "fairness", allowing political promises to be honored with cash paid to voters directly as "entitlements". Next on deck, the nation's medical care industry will be taken over as a gov't provided "service" to "save money". What happened to the days of limitted gov't and eumerated powers?
