Robin Hood and His Band of Green Thieves

Remember the basic premise of Robin Hood? The rich king and his fellow nobles were exploiting the poor through excessive taxation and oppressive application of the laws of the land.
Robin Hood and his merry men embarked on a novel scheme to steal from the rich and redistribute the loot to the poor through a variety of clever means. Their outlaw hideouts were deep in the forests of England and their “uniform” was green in order to mask themselves most effectively.
Green is certainly the in vogue color, and many in the environmental movement would love to have the general public believe that the Robin Hood philosophy of redistributing income from rich to poor is their modus operandi too.
Perhaps some simple comparing and contrasting would allow us to determine whether this claim stands up to any scrutiny.
