Failed businesses also tend to provide lower returns on capital, and that’s totally backed up by data. Doesn’t mean the “purpose” of those companies was to provide lower returns on capital.
It's a very meaningful statement when people claim that thing X's purpose is Y which is good, and therefore thing X is good, even though the actual outcome Z is not Y and in fact may be diametrically opposed to Y. Happens quite often.
I don't know if it really applies to the current thread, but I just wanted to point out that POSIWID is certainly not a vapid, empty concept.
