Age has everything to do with it and if you don’t realise that then you are generationally blinded and becoming a grumpy old cliche.
Every generation criticises the younger generation and its fads and objects because it doesn’t fit with their own experiences when they were raised as kids.
As to who are to blame, we are, as parents we mollycoddled our kids driving them to schools in our cars, overprotecting them, passing the phone to them when they are babies saying watch TV for five mins while I take a break, giving in to peer pressure at school and buying them the latest ADIDAS, or Apple SmartWatch.
And the most stupid thing out of all this is after years of being driven to school in our big 4x4 cars to school, looking after them with air-conditioning and heating in our homes or whatever luxury things we add, which to be honest we don’t really need; if they dare to stand up and worry about the environment we tell them to stop being so stupid and shut up. 
The next time you criticise this generation, open up your thinking and try and think objectively and ask yourself who is actually to blame. At the age of 46, even I start to think like this but I check myself and stop, not all the time I admit, as I am only human, but I really try to keep objective thinking as my main thought process.
The older generation has always criticised the younger generation thought-out history and will continue to do, because of narrow blinkered thinking. Funny that eh…!!!
