Being a doctor is a very profitable and respectable profession. With that said, doctors are available everywhere, they are available in categories as in if you have a problem relating to heart you would consult a cardiologist; if your baby is not well you’ll consult a pediatrician and so on. They even come in a range starting from Rs 50 to whopping Rs 1000 per visit.
On the contrary, if you have a problem in your kitchen sink and if you are not good with tools, odds are that you’ll either search a plumber if you do not already have one or you die trying to call him. If you are really lucky your problem would be solved before evening.
Plumbing is very expensive even in European countries as well and people only call them if they are not able to handle the problem anymore. Both professions are valuable, we need both of them with a great sense of urgency, yet one is available in plenty and another one is so scarce.
