that statement is neither necessarily true nor necessarily false - corporations and the government are bureaucracies. Sometimes one is better, sometimes the other is.
For example the National Weather Service kicks the living crap out of every private company trying to do the same thing. They pay well, the recruit the best and brightest, they are managed by professionals with experience doing what their underlings do [something you often only can DREAM of in the corporate world or the government world].
Medicare is another example - it's operating overhead is 4%. The operating overhead of private "insurance" (sorry, it's fraud, not insurance anymore) is a whopping 30% MINIMUM.
On the other hand there are some things private industry IS better at doing, and the government quite often contracts out to these people - construction comes to mind, software development, etc.
The government, when run by skilled people, tends to be much better at private industry than doing things that are "natural monopolies" (police, fire, roads, water, etc) or things the profit-motive would harm [like insurance].
