John Goodman explains how ObamaCare increases demand for medical care with out increasing the supply:

[R]ationing problems will be much more severe than they are today. If the economic studies are correct, 32 million newly insured will try to double their consumption of medical care.  Plus, almost everyone else is going to be forced to have more generous coverage than they otherwise would have selected. The result:  in just two years expect a huge increase in demand, even though the legislation does nothing to increase supply.
