One of the problems with our system of government is the accumulation of laws over the past 200+ years.
We clearly need a Constitutional Amendment requiring that all laws expire after a certain amount of time (say 7 years).
Obvious laws such as making it illegal to commit murder and other violent crimes would have no problem in being renewed. More contentious laws due to their dubious constitutionality such as Gun Control Laws..would expire and most likely not be renewed.
There are plenty of other problems..but I think this is one of the main reasons why things go to hell over time: is accumulation of outdated and/or unconstitutional legislation
