I gather that personal electronics are largely to blame, along with sensation of flying diminishing. Back in the 1950's and 1960's, the only personal electronics were radios. Advent of the transistor allowed for relatively inexpensive pocket transistor radios, but one could listen to music on the bench while doing other things, building model planes, during breaks from flying. Then, aircraft were still relatively new technology, especially with advent of jets, helicopters and missiles. There was some TV watching, but most kids played after school. Texting consisted of those with Ham radio interests in the form of Morse Code, which only a minority did. Modern cell phones are computers with streaming video capability, along with impersonal texting and calling to communicate. No longer does one need to visit others (like after school) to socialize (play).
Sometime back, a friend, also a good Christian minister told us, WW1 took the Daddy away. WW2 took the Mommy away. Now, the government wants to take the kids away. In some ways, considering all the non-beneficial societal agendas around us becoming more exposed, that seems to hold a good bit of truth. However, now I am deviating into political debate, and thus I stop.
I think that there will still be a few kids interested (not all). Dane Martin's kids are involved, which goes to show that with the right prompting, kids can be involved. Singapore and Malaysia have high school clubs with CL fliers involved. General selfish nature of a few in our society who have prevented flying in public places considered previously adequate in the 1960s and 1950s aside, with the right type of people gifted in working with children, I think a lot of beneficial good can occur to involve children in CL activities. Thus, we shouldn't give up, but where opportunities occur, with gentle prodding, encourage the youth. Who knows, we can sow positive things into young adult's lives, give them things they would never have experienced otherwise, which they can carry with them into adulthood.
