This talk about one generation pooing on the next is just small potatoes anyway. If you really want to talk about generational gaps, look at how ancient man had to live vs people from the last 100 years.
-Ancient man had to kill his meal first with weapons carved from wood/stone, modern man has to push a heavy shopping cart on a tile floor, and uses a pocket knife to cut open the food packaging on occasion.
-Ancient man fought off bacterial disease from unclean meat/water when he was lucky enough to find it, modern man gets the sniffles and a tummy ache from eating too much.
-Ancient man had to protect land/tribe or settle disputes through hard battle, modern man has a lawyer sign binding litigation settlements for him.
-Ancient man fought against weather and natural predators (even dinosaurs...I saw it on 'The Flintstones'), while modern man turns up his thermostat and calls an exterminator.
-Ancient man built stuff with his bare hands, modern man turns on the assembly line power or the 3D printer.
-Ancient man sent messages to far away tribes by walking there and telling them in person, modern man sends a text in between watching a stupid video and taking a selfie.
I think ancient man kicks modern man's tail, even if their music was a bunch of guttural, off-key moaning.
