1. The government provides needed services more efficiently than private business can.
That is a fact you can see in your own bank account.
These services still cost money though. Think of emergency services as insurance. You pay for insurance, whether you use that insurance or not, correct? Well, think of government services the same way.
For the people themselves providing those services, those are paying jobs. Jobs, the same as in the private sector. They pay taxes, social security, retirement. Pay rent/mortgage, the same as people in the private sector. The only real difference is they work for the local, state or federal government.
Government services do not need to make a profit. They do not need a very highly paid CEO, bonuses, stocks and bond holders to keep in mind. Prime time advertizing, etc. All this has to be paid for by the customer. So how can private enterprise even compete with keeping the costs down.
The fact is they can't. Not only that, they won't because management keeps going after that ever more profit, so they can pay themselves even more.
Think of our health care insurance as the worst case example here.
