Why only big cities should have quality healthcare centres

If you notice,big cities have number of speciality and super speciality centres.Infact the condition is such that they are overserved.Where as if we move to tier 2 or tier 3 cities,there is clear lack of quality healthcare centres which leads to people from these cities flocking to nearest metro for quality treatment.But the question arises why quality healthcare centres don't come up in tier 2 cities even when there is requirement for them?The basic reason is matching infrastructure is missing.But this can be covered to certain extent if government gives tax incentives for starting healthcare centres similar to what it gives to the industry.It will make setting up of quality healthcare centre in smaller cities viable as well as help the people get access to quality care in their cities itself.It may be late for today's budget but government can think of implementing this idea in near future.
