Great post Thunder II, appreciate the insight and thought you put into this.
I've only been collecting Gas & Oil since 2006. However, I've been into muscle cars since the mid 80's (high school days).
I observed the same happen in the muscle car scene. From a tight knit group of friends sharing a common interest and passion it devolved into a cut throat, disrespectful, highly competitive, envious and jealous bunch.
I think the root cause is two fold one is a deterioration of values, morals and ethics generally in today's society. The second being the economy and people looking for new sources of income. They are void of the passion of collecting and have no attachment to this hobby or the people in this hobby. They are driven by "net profit". When one is driven by profit (greed) they are blind to many things. Courtesy, etiquette, common sense, morals, ethics, and professionalism are not important to them.
What is really sad is that rather then be turned off by these individuals many simply choose to become like them. We should all stand our ground and see these times and individuals as examples of what we don't want to be and avoid becoming that. IT IS OUR ACTIONS, THAT DETERMINE WHO WE ARE. If we take ownership of who we are and stay true to what we know is right; We can turn this around. It is easier to become part of the decay, rather then stand our ground.
This is just a general observation on my part and not directed at anyone in particular. It is just food for thought and hopefully a cause for all of us to reflect on ourselves and worry less about everyone else!
Have a great weekend.
