Why the truth is not in them ??

No need to over analyze this phenomenon with talk of neo-Marxism. What the OP describes is age-old tire-kicking and buyer's remorse. It's nothing new and pervades in audio transactions because audiophiles tend to suffer from neuroticism. Unfortunately, many of them also lack the back bone necessary to explain to a seller that they had a change of heart. 

sonetduo,

And what if cal91 fulfills all the criteria you require from him? Will you bow down?

Maybe I’ve just been lucky.
I ‘ve interacted w sometimes met ( purchasing/ picking up gear in person) a lot of really nice folks.
If it sounds/ feels fishy, I don’t bite.
maybe I’ve missed out on those deals that were “too good to be true,” but can’t say I’ve lost much sleep over that.

Democratic socialist countries like Norway, Denmark, Sweden, etc., report far higher levels of both trust in their own governments and in their own levels of personal happiness than capitalist Thunderdomes like the US (or the UK for that matter)-- and that is a long documented multi-sourced fact. BTW Marxism has nothing to due with Nazism-- again a well understood fact. Those that are making these kind of connections are, to be kind, poorly informed. Meanwhile, back here in the good old US, people report vastly lower levels of trust or happiness. Social and economic mobility is also far far higher in those and other more socialist countries (and no, sadly, Russia is not among that group, as they're not a socialist country). Any questions?

Very good and right on the center...No  questions for me.... Thanks

I will ad Finland and Iceland....

None of these countries are banana republic either..... :)
