~ Gambling industry is really become profitable due to this behavior.
Gambling industry doesn't profit from people's illnesses, it profits from the house edge. In fact, if there were no gambling addicts, and, as a consequence, less governmental restrictions, gambling industry would only benefit from it. So, compulsive gamblers cause harm not only to them and their families, but to the gambling industry as well.
This is something I agree with, it may seem on the surface that the gambling industry takes advantage of those that become addicted to gambling but if it was not for them then gambling will not have as much of a bad reputation as it has now, in my country it is still very common to find people that have a very negative attitude to the casinos and the people that play in them, when the truth is that the majority of the gamblers are just normal people that gamble responsibly once in a while.
