every engineer, doctor, lawyer, nurse, businessman

You're getting very confused. None of those people you mentioned are educated in the social structures and political systems of the world. It's easy to continue exploiting people who are not educated in these fields, because they are largely oblivious to it. Would you sit here defending the engineers and doctors who contributed to the Nazi war machine? Because -- and I'm not sure if you're aware of this -- most of those guys were hung.

You are so arrogant and yet so unintelligent, my friend. You are explosively keen to lambast the individual, without so much as giving a single thought to the system they are being expected to contribute to. Not once does the thought cross your mind that the present way of doing things might be exploitative, counterproductive or deeply unjust. It is unfortunate that you lack the computing power to overcome your own brainwashing, because otherwise you might consider that it is the system which is supposed to be of benefit to the individual, not the individual who is supposed to be of benefit to the system. You have been inculcated into a cult of system worship and you are incapable of seeing humanity as anything more than cogs to power that system. If a particular cog is either incapable or unwilling to dedicate its life to powering a machine which doesn't even benefit them, you believe it should be thrown away or shamed into compliance. And this is exactly the same ideology proliferated by the Nazis.

I mean, just for a single moment consider the insanity of your belief system. If a person refuses to permit themselves to be exploited, rather than treat that person like a hero, you attempt to use it as a form of attack. Your mind has been twisted inside out.

I haven't wasted anything. Stop projecting your own expectations and false beliefs onto other people. It's clear from your language that you are a deeply bitter individual and if what you are saying were true, it would be the other way around.
