That's a bit like saying that Donald Trump would make a great neurosurgeon because he's a successful reality TV star. Countries and businesses are not the same thing. I would think that would be immediately obvious to the casual observer, but apparently it's not.
Consider the case of public schooling v. private schooling in America. (No idea how that plays out in other countries.) Private schools almost always have higher rates of graduation and higher test scores than public schools. Every so often somebody comes across this fact and declares that we should just abolish the public school system and make all schools private. This suggestions makes the public schools freak out, well, publicly, while the private schools freak out quietly in a corner.
Why are the private schools freaking out? There's a reason private schools outperform public schools: they can choose their students. Private schools already have the advantage in that any child with parents who have the money and motivation to spend thousands of dollars a year on their education is starting from a place of privilege, but the big advantage private schools have is that if those children turn out to be poor performers, the private school can boot them out- to the public schools.
Public schools are required to take everyone, poor performers, troublemakers to a certain point, poor children, children whose parents couldn't care less, etc. Of course private schools outperform public schools. Being surprised about that is like walking around at the Olympics and being surprised at the low levels of obesity.
Business and government are the same way. Businesses have the option to drop poorly performing products and employees. Guitar Hero just isn't bringing in the profits anymore? It's gone. Bob hasn't finished a project on time in two years? Bye bye, Bob!
Governing a country doesn't work the same way. Those poor performers? The homeless, the addicts, the poor, the sick? They're called citizens and you can't get rid of them because they're bringing down the bottom line. (Well, you can, but then people start using words like "tribunal" and "crimes against humanity" and suddenly a trip to Switzerland* is out of the question.)
Anybody who thinks a country should be run like a business is under the delusion that they'll be on top their entire lives and misfortune will never happen to them. Good luck with that.
*I originally typed "Sweden", it is Switzerland W. can't visit. (In my mind, the whole north of Europe is lumped together into one big zone of cold, although the Swiss do have the chocolate.)
