Why big hospitals are overcrowded, small hospitals are cold and quiet?

Large hospitals are overcrowded, small hospitals are cold and quiet, this is not a very normal thing, because people aspire to be able to treat their own disease, and then will find a large hospital, because their facilities and equipment is more complete, but if you say you only find a small hospital, his facilities and equipment is not complete, and then the treatment of the disease, then may not be so good.
