Wow, sounds like the beginning of a novel. But here's my 2 cents.
When I started bass fishing, my dad and grandparents had pretty good equipment for the time. Johnson spin cast reels, fiber glass rods, a couple of lazy ikes, hula poppers, spoons, and pre-rigged worms with two or three small hooks and a little spinner on the front. I was probably around 3 or 4 when I got 'hooked'.
I've gone from the Johnsons, to zebco spincasts, to 1310 mgs, to high dollar shimanos.
I think technology has definately increased my ability to catch fish. Flashers to gps/fish finders. Wimpy fiberglass rods to composite. Castability and drags on reels. Cotton line to whatever you want line. Fishing forums instead of learning from one or two people. Trolling motors instead of oars.
Fishing has a definate impact on my life. 90% of my vacation time is spent fishing, mainly in Texas. I live on an old mining strip pit with my boat dock 23 steps from my back door. I own three boats and two tow vehicles. (Wife won't let me put a hitch on hers) I used to play golf 5 to 6 times a week, now maybe once a week. Two thirds of my internet time is spent on fishing stuff. Our storm shelter is "Jon's tackle shop".
I used to fish a lot of tournaments, but now mainly just enjoy getting out. Fished for two years "professionally", but got tired of sleeping in the camper shell of my truck half the time. LOL
I think in general fishing has improved. However, with all the idiots any more, finding new ponds or tanks to fish has become practically impossible.
I believe fishing has improved my quality of life. I can get away and not think about any thing but trying to fool a bass into biting. My wife loves to fish now, which gives us quality time without doing other things men hate to do! My daughter in law has gotten into it as well as one of my grand daughters.
I guess I am grateful that my dad and grand parents started taking me fishing at an early age. There are values to be taught, quality time with family and nature, and a break from the stresses of work and life in general.
I hope this is what you wanted. Like I said, I think you could write a book on these questions, and I'll be interested to see what other responses you get.
