The problem is one of usurpation of the agreement. The Founders went to great lengths to make it difficult to make changes without approval by a majority of the people served or a super-majority of their elected representatives. The lust for power of those representatives has proved to me stronger than the People's desire to hold them to the scope of the original agreement. This is most important on the federal level because in a practical sense, individuals have no recourse.
On the state and local level the individual has a recourse. States and municipalities are effectively "products" that one can compare against its competition then decide which to purchase.
Absolutely. That lust for power is that greed that I was talking about earlier, too. Even when it is held in check, it's still dangerous.
I lucked out and got a good deal where I live!
