Nonsense. The clinicians working in the healthcare system have zero incentive to keep patients chronically ill. This isn't a matter of keeping patients coming back: most doctors already have more workload than they can even handle.

Most chronic diseases are primarily caused by lifestyle choices. This is largely outside the scope of medical practice. A doctor can prescribe metformin to treat type-2 diabetes and a statin to reduce cholesterol but they can't force you to clean up your diet and get some exercise.
