It's dangerous to work for gambling-related businesses. I assume most, if not all, people there are psychopaths. (How about public a.k.a. share-price-driven companies? Most companies?)
Been offered to work for one before, turned it down to protect my religious reputation. Turns out, protecting this reputation protects my life, too. Reputation is everything, says one of the 48 Laws of Power.
Someone I know worked for a company whose client is a casino. Also had psychopaths of their own. Or there are just a lot of psychopaths at the top?
