Not in any economic sense you may have thought, given the attention oft given to, e.g., the 1% or 99% (We Are-; Occupy-style) where now the 90% might be the disappeared middle class in the US that extended from the bottom 10% – that was around even in the best of times – all the way to the top — excepting the 0.01% that was in charge all the time …
Here, it’s about a quote slash truism:
90% of everything is crap
Have ever truer things been said. This, of course you knew since prep school, being Sturgeon’s Law.
Just putting it there. See the link for a ‘proof’. Or look around you; physically (co-workers), mentally (in your head, and feel free to assume the others’ heads are not necessarily better…), qua your pay check, your significant other [hey here I can testify I’m lucky with a not-90% specimen par excellence; no she’s not reading this], etc.
