From my experience it's because the right preside over, what can only be described as, a pyramid scheme. A system for funnelling money away from the people that generate it, and putting it somewhere they can no longer benefit from it. The right become self appointed arbiters of society because they hoard and hide the wealth. It takes a real broken mind to operate like that and requires frequent use of the most base and offensive human traits.

its easy to damage people by being ill minded and usurping power to your own ends, and those of your caste.

The problem the left has is that they think of all the same ill minded pursuits, but couldn't bring themselves to implement them, because they are for the collective, not the individual.

The left are the providers, the workers, the contributers. The right are the takers, the exploiters, the enslavers. The left are strong, the right are weak. The left provide, the right depend on this provision as they contribute nothing to social achievement. Only weakness and dependency allow you to make the call to damage others for the benefit of yourself and the small minority that surround you.

The calculation is simple. If your actions are to the benefit of the masses, without having first detrimented them with an attack. These actions are just and fair and moral. If you wait for other people to create and build, then collude with your ilk to usurp that contribution, so that it benefits your collective moreso than the people that generated it. You're wrong, unjust and immoral.

So its not that they don't understand, its that they cannot bring themselves to believe people are capable of conducting themselves it in such a way, as to detriment everything, even our own habitat, for meagre gains over their fellow humans.

Snowden is a classic case, where people still refuse to believe they're being spied on and listened to for right wing agendas. We can even go back as far as the sinking of the Lusitania, which was the catylyst for joining the war and corporations profitting from the sale of bombs, bullets and guns.

Its not that they cant see, its that they refuse to accept this level of corruption exists in peoples minds. Plus the endless media bombardment legitimising all the hatred and immorality, while demonising social endeavours.
