Rereading this, I felt the need to put a disclaimer up here. I'm not angry, I'm offended. I'm frustrated.
So, I'm 23 years old. My wife is 22. We're saving up to buy a house. We graduated college this past May. My first dive was when I was 11, I was certified at 13. She was certified at 20. I paid for her certification, a trip for both of us to Roatan, full sets of gear for us (including a lot of Tech/Cave stuff for me), Cavern/Intro for me. I paid for 3 NC wreck trips (2 for me, 1 for her). Scuba is also not my only hobby. Since I've gotten a job, my expenditures have increased....and we're still on track to saving for a big down payment. My college degree was in Aerospace Engineering at Virginia Tech. It's one of the hardest Bachelor's Degrees to get. I worked my tail off in school and out of school to afford doing what I want. I graduated into a job market where the job placement was the worst Virginia Tech has had in decades. College tuition is at an all-time high, growing exponentially. The expectations put upon people is higher now than it ever has been (lots of studies actually attributing a huge increase in suicides to this factor alone), the pace is faster than it has been and it's expected of me to not only keep up but stay ahead of all advances. My usage of a smart phone isn't a "want"...it's a necessity. I use my phone for more than many people use their computers, as it's expected of me. I am very politically informed. I enjoy the intricacies of sports more than the basics, and I devote rather than "bucket list". I have competed internationally in a MULTITUDE of sports, and have reached rather exclusive heights in multiple hobbies (Cave Diving, for example).
Having said that, I hope everyone here understands how offended I am by the talks of youth being irresponsible, lazy, broke, or what have you. I play video games on occasion, sure.....but normally it's been at 4AM after having worked for 46 consecutive hours and being too wound up to be able to go to sleep before being expected to start back over at 8AM. Disparaging people collectively because of age is as offensive and as discriminatory as racial or religious prejudices. There are plenty of people my age that fit your description, but there are also plenty of examples of people of older generations that have been worse than any example listed. Example? My tax money is going into Social Security. The elderly are drawing on it. Am I ever going to see a dime of it? NOPE.
I think there are a few contributing factors to why there aren't as many of "us" in the diving scene. One is definitely cost. I was fortunate enough to have supportive parents that were willing and able to pay for my "needs" as I went through college, so that my funds were for my "wants," where many other students aren't that fortunate. Working >100hrs a week every week means very little time for an income, and that's for those fortunate enough to be able to afford college in the first place. Those that can't afford college now are at a significant disadvantage when it comes to finding high paying jobs, moreso now than ever before. The jobs we DO have are expecting more from us than ever before, and because of the economy we're forced to work harder because someone with more experience and the same degree as me is willing to do it for the same price. Another reason is because of people similar to a lot of the opinions in this thread. I'm half your age, so clearly I can't be a "serious" diver? I've seen more elderly divers think they were good/experienced that ended up being disgraceful in the water than youth....but the youth still have to deal these negative attitudes? I haven't experienced this much while actually diving, but I've heard a lot of "barking" above the water. Another serious factor is the internet. I've heard of more things through the internet than I have without it. Red Bull Flugtag? Zorbing? I wouldn't have heard of these things without the internet. It gives me a MUCH wider range of options. Plus, as tiny as the world is now it's really easy to get to other things and hear about things from other places. With the tiny amounts of time and money we "youth" have, there are too many other good options to spend our time and money.
