No matter how much money you have or how affluent your community is, you need Doctors, car mechanics, plumbers, HVAC techs, and yea, even lawyers unfortuantely.
You don't need pawn shops, they look for people down on their luck and sell to those that aren't. It is the very nature of the beast.
We will start with you don't need a car mechanic because you can walk, you don't need a plumber because you can always dig a hole, though you may violate some laws.

You also do not need HVAC techs, or even lawyers. Life can continue without any of these services. Now, for the doctor, one can also do without a doctor, though one could die from some illness, but then again a home remedy may also heal one.
My point is many professions provide services based on others bad luck, or whatever. No one is forced to walk into a Pawn Shop. In my life I have never pawned or sold any item to a Pawn Shop. I have purchased a number of items from them though. I just don't see why one would be so against the business. If you get a loan from one, the interest rate, and all other conditions are in writing. If one does not read the conditions of obtaining the loan, then shame on them. If one does not like the contract, then they are free to walk away. I have never heard of someone being forced to pawn an item because the Pawn Shop owner had a gun to their head. Though someone will probably Google it and find one instance where is has happened.

The bottom line is if you don't like the service, don't do business with them. I don't see any reason to bash the business.
