> The US series Breaking Bad talks about a well-behaved chemistry teacher who resorts to manufacturing and selling drugs after he gets cancer and finds out that his savings are no where close to covering the medical cost

At the risk of going off topic, this is a popular, but incorrect meme. Walter could have had enough money for his cancer treatment, especially after getting the offer of paying it off by his former cofounders. He started selling drugs to provide for his family because his cancer was terminal. (And continued because of his own hubris.)
