@georgeob1,
Let's go over your list:
Transportation Security Agency (TSA): They check everyone before boarding a plane to make sure they are not carrying anything to hurt anyone on the plane.
I feel more secure flying because of the TSA, and wouldn't have it any other way.
DMV office: Issues licenses and renewals to drive vehicles. They make sure that the individual applying for a drivers license meets the requirements to drive on the public roadways. I see this as a plus.
Bank, credit card agency: They need to make sure that the individual who withdraws money from the bank is authorized to do so. Also, the credit card issuer needs to make sure that the user of the credit card is able to pay the balance of any charge made on the credit card.
Most retail merchants in the country issue credit cards to cut the cost of processing, because credit card companies charge a fee which reduces the merchants margin of profit. I think American Express has the highest fee, and many merchants refuse to accept American Express cards.
