Our Constitution, whatever its perceived flaws, is far better than the constitution of Great Britain. It has NONE.
There are no constitutional restraints on the raw power of the English government. NONE. Hence the arrival of the welfare state and socialized medicine in England. Hence the decline and fall of the secular and drunken British state.
Unfortunately we no longer have any constitutional restraints on the power of the US government either. The welfare state has been growing by leaps and bounds here for at least 70 years now. There are just too many people who demand that the government take care of them, and too many of them are cheerfully willing to give up all of their rights if it means getting such care.
