Right. Easy money earned effortlessly often goes away just as easily. The most obvious example is winning at a casino, which is often lost.
I find it very wrong when people refer to winning on a casino as easy money. I don't ever think so because you spend time and energy there trying your luck and most times these people have lost a fortune before finally hitting one themselves as profits and compensation.
Those who squander their gambling wins are just careless people naturally, if we know how hard it is sometimes and the emotional, financial, physical and psychological investment done in gambling, especially physical casinos, we would never refer to it as an easy money.
This is often the case with inheritance. The heirs squander the fortune, and their children end up with nothing. One could argue that now 80% of the wealth in the world is not earned, but inherited. Yes, but this is only a part, let's say 1/5, and 4/5 of the hereditary mass is squandered and lost by the heirs. Those heirs who have retained their wealth have made at least some efforts of their own. In general, this order of things is not bad at all, because everything should be updated, and money should change hands to more worthy ones (ideally).
I can agree for inheritance since most of them have little or nothing to do and still have fortunes handed over to them. wise rich people now always ensure their heirs are capable of handling their inheritance prior to handing it over through skilled training and direct mentorships of their heirs, even having them trained in the family business and operate it alongside their parents.
