Saudi Arabia demonstrates the overlap that exists between government and business, there is a sort of family business that runs the nation and affiliated businesses that own everything else.
There isn't much difference between a business and a government in the money respect except for one thing, governments do not really have a profit motive. This is a sad lack on the government side , without a profit motive there is almost no limit on silliness and unsupportable waste, wasteful businesses loose customers to better run businesses, there is no equivalent check on government waste until war of conquest puts more effective government up.
Government regulation is needed , but ought to be pared back to the bare need , anti trust laws are the most beneficial of them all, but we are somehow allowing companies to get too large to (allow to)fail .
I think anytime the businesses are so large that having one of them fail becomes a national tragedy , there ought to be a process to measure and cut the thing in two. The opposite thing has happened too often , as when Boeing ate McDonald Douglas leaving us now with just about one manufacturer of large airframes.
Centralizing authority and power in government too much is a very similar problem.
