A businessman comes to be a national leader...

When we saw a lot of comment like this:

CNN: Donald Trump is running the White House like a business. That's the problem

Bloomberg Opinion: Trump runs the government like his business. That's the problem

Most of the discussions, businessmen should not run a country.

But when I am searching for by entering 'businessman run for leader in the world', the top 20 peoples shows you that most of them are well-known successful businessmen in the world.

So businessmen are not a problem ...

Compared with the government, problems faced by an enterprise may be similar. 
Different will be on the scale of the problem.

But what I want to say, survival is the basis of the enterprise because its life cycle can be shorter than 30 days.

Businessmen are in training every second.  Basis instincts will drive them with no doubt and aggressive to solve the existing problem in time.
