It is a depressing state of affairs.
To add on to your point about people playing around behind closed doors: something I've found quite surprising is the remarkable skill and effort that is involved in playing around. I know people who are extraordinarily talented at making themselves look busy and/or productive, but in reality are merely a drag on their company and the wider economy.
In one sense, this is a type of fraud the market is supposed to self-correct (i.e. identify and remove). This fraud seems to be increasing.
I'm often reminded of certain types of deceit which increased in the Great Depression. It was not uncommon for a husband, say, to dress up and go off to work in the morning, and return home as if he had had a normal day on the 'job'. In reality, he was unemployed, and either looking for work or wasting his time doing something else. This would go on for 1-3 years as the family savings was gradually depleted to nothing, while neighbors and family members thought everything was fine. Then, when the deceit couldn't be sustained, the husband tried operating a mini-golf business (doomed from the start) out of the front yard.
