TBH, I think it's not just children taking things for granted. The internet, apps and other technology has made a lot of people of different generations expect everything to just work instantly and automatically and they just can't understand that some things aren't possible, may take a long time or have to be done by actual people with feelings, who would like to be treated as such and thanked for their help.
I remember reading a sweet story online some time ago about somebody's elderly relative making her first foray into using the internet and, instead of typing, say, "cinema times Preston" into Google, she would type something like "Could you please help me find the film showing times at the Odeon in Preston, because I'd like to go there with my friend Doris on Tuesday if she's not too tired" and then, having found the results, would go back into the Google box and type "Thank you very much for your help"! I think it's tipped too far the other way now - instead of treating an algorithm like a human, some people automatically treat people like algorithms.
When I tell my son that I didn't have a computer until I was 16 - and certainly no internet, and that I was 18 before there was a 5th TV channel available, he's wide-eyed with surprise as these are just such normal everyday things for him now. I don't think he's doing anything wrong, though - I don't blame a young child for being a young child.
My grandmother was born before TV was actually invented, but that doesn't mean that I didn't take it (albeit with only three channels) for granted as a young child.
I can't begin to imagine what national service and conscription or being ordered to take on whatever jobs were deemed necessary for the war effort must have been like. I just take it for granted that, within reason, I have a fairly wide scope of options from which to choose for myself what I want to do for a living.
Am I guilty for taking it for granted that, if I decided to put some railings up around the front of my garden, they would not be cut down by the authorities and used to make bombers?!
Are today's young female employees wrong to take it for granted that having a baby doesn't automatically signal the end of their working career (outside the home) - or that they should receive the same pay for the same job as a man?
