"As for the notion that giving a task to a group of 18 to 20 year olds will get the job done quicker and more efficiently than under *normal* rules, HA HA HA ! I can tell you *from experience* that is simply untrue. You may find in a group of 20 people that 1 tries hard and is semi-competent, 3 or 4 will try but are totally incompetent and the rest will slack off when no-one's looking. None of them will have any common sense whatsoever. Apart from the first 4 or 5, the rest will claim "it doesn't matter"."
1.) Careful with your use of stereotypes. There are plenty of 18-20 year olds who can and would do it better, as there are plenty who wouldn't. It's not a 1 in 20. Not everyone will throw it all away for a shiny car, a beautiful face, and a quick high. Yes, there are many who would, but not as many as you seem to think.
"We built this world for you to continue building upon. We've tried to give you a decent foundation, tried to prevent you making stupid mistakes and repeating past work. But you seem hell bent on ripping it all up just because you think you know better."
2.) You seem to think you have built up quite the "foundation" for the young to start from. Look at the world around you. It ain't perfect by any definition. What exactly qualifies as making a good foundation to you? I get to come into a world stuck in a global depression with a completely unreasonable government and filled with amoral people. Maybe you're misinterpreting "ripping it all up" for trying to fix some of your mistakes.
