Without government planes would crash into each other all day and fall out the sky. Nobody would know how to handle anything.
All too typical.
a lot of times the government can help matters because they have the money, and the resources, the flood victims, hurricane sandy victims, government helped a great deal with 911.
if you let the private sector handle things, they fail.
for instance the privatization of the prison system failed miserably. and will now be disbanded.
The government doesn't have money and resources. It has a legal monopoly on the use of violence. It uses force to steal money by force from people and then takes a cut towards itself and redistributes the money to others. It only has what it takes through taxation.
Privatization isn't the same as free market. Government contractors are paid by the government. That's government subsidized. Socialized costs with private profits. That's bad.
If a real private business that's not government subsidized were to fail at something, it's ok. Other competitors can always take over depending on the business. If the government fails, tax payers eat the bill. If the government fails, it doesn't go out of business. The government will simply demand more funding instead. The government can't file for bankruptcy usually, which means they'll go further into debt, which means more damage done, using up resources inefficiently.
