Dunno about that. I ride my bike all over god's green apple, and I see no shortage of $5,000 bikes. I see plenty of hiking/camping/kayaking stores... and good luck getting a tee-time around here.
And the median home price in your area of NJ is what? (Or is "god's green apple" the whole US?)
Call me Captain Obvious, but I think we have to look at this question as an average over the whole US (or world, as some have suggested).
