Steve, that is a great point that I had not considered as a factor in the diminishing loyalty of newer generations. Greed, in one form or another, observed in their upbringing in the 80s and 90s, landed their thinking in a different spot than yours and mine.
Another point is the diverse economy we live in - you are right - it is more about what YOU do and what YOU bring to the team and how much you value yourself that drives behavior among the younger people. Please do not misinterpret - this is no necessarily selfishness, rather learned norms and survival tactics in how this world does business in 2018.
One more point about the economy that will probably hurt motorcycling - it is a sharing economy - from transportation, to boating, to workspaces - companies like Uber, and Boat Club USA, and We Work all make it so you do not have to invest a disproportional amount of your income to things that get limited use or offer limited value. Tie up $30 grand on a motorcycle that sits in my garage at least 1/3 of the year? It does seem foolish, doesn't it...
