You say it well and I agree, they're missing out and don't even know it and the effects of that will be far-reaching. The sad thing is that parents who grew up like that are now teaching their kids the same thing and worse and so the cycle continues.
I know that times change, but when did manners become unfashionable, a good work ethic, the ability to entertain oneself, inquisitiveness and so on.
So sad.
