Yes, there are too many market forces keeping the prices down. It's a race to the bottom. People, stop all this miserly shopping for the cheapest medical care! Sure, your tiny Wal-Care bills look attractive but have you considered that if you keep doing this, you're going to cut more mom'n'pop providers out unless they are also able to viciously cut costs?
We need to put Wal-Care (and other super-slim-margin health care providers) out of business, in order to protect the health care profession!
