The founders created a minimal government as it was the ONLY way to restrain it from becoming a criminal enterprise. They wisely realized that making the government responsible for only a select few things was the ONLY way to keep it properly constrained. Sure, that means that the welfare and aggressive warfare functions of the government were to be non-existent, but that independence is the real price of freedom.
But over time, the country filled up with dumbfounded dipshits who couldn't absorb or remember that one principle lesson.
In closing, if America goes to hell, at least we will know why. It will have been the combination of political avarice and incorrigible stupidity.
