You may be right, I've never been diagnosed and put on CPAP personally and can't say whether that is true or not. But in general the western medicine has come to a point that it tends to offer solutions that are quite good at reducing the symptoms and generally don't address the underlying cause. It may be incompetence of the system or it may as well be financial incentives, slightly steered towards not providing a cure and but milking the patients for more money with symptom reducers. But on you're right on one thing though, a lot patients are lazy and would choose the quick fix over doing some of the work themselves.
