I don't agree at all...
Sure, there are video games now that now compete for a slice of kid time..So you don't get kids playing sports all day because there are a ton of other things to do.....baseball used to be the only thing kids played in the summer..now kids play other sports as well...like soccer,
I don't think that is the story at all
To me, the biggest difference is that sports are much more organized than they used to be. No more pick up games..everyone has to belong to a league..or multiple leagues. Kids don't call each other up to play baseball in the back yard or stick ball in the street anymore....now days, they text each other about when the next game is on their schedule.
the move to more organized sports play has propelled a whole new amateur sports industry....and have cost parents a fortune, especially for travel teams. On the flip side, it has made skill development more organized and more supervised, with amateur and professional coaches (and training aids) watching over every form of skill development.
I think this does two things..
1. it funnels out kids much faster than the good ole days..so not as many kids play a given sport (like baseball) as it was in the past. If you look across all sports at the youth level, most participation is declining even as the pro leagues earn much more money. There are some exceptions like soccer and lacrosse, but these sports started from a very small base and are only growing because of penetration...All the marketing guys that follwo this stuff believe once they hit a threshold, these sports will level off as well.
2. the kids that are playing are much more commited and develop their skills much faster, more efficeintly, and at much greater expense than it used to be. There is so much instruction out there avialble for anyone who has the money to buy it. ANd it is now year round, competing with other sports...Serious hockey players can no longer play baseball because of spring leagues, etc.
Is it better? is it worse? I guess that depends. kids that would have played multiple sports through HS in the old days find that they have to choose one over the other much sooner (for time and financial reasons) and kids that were maybe not as athletically gifted no longer have as many avenues to play becuase they withdraw from the rat race or take up other things that they can be good at. (unfortunatly..video games) or "alternative" sports like skateboarding, skiing,, or LMFAO.....competative eating ( I am not kidding!)
