Unjustified Price - Brown Rice

Brown rice is produced when only the outermost layer of a grain of rice (husk) is removed. While to produce white rice, the next layers underneath the husk are removed.

Since the less processing steps are required to produce brown rice, why the price of brown rice at the markets are almost double than the white rice?

Ways toward healthy diet could be in lower cost without the unjustified price hike.

Brown rice is a greener choice too, it's basically down to processing - the less processing of a food, the less energy required. I can't imagine how many processing steps (maybe chemical process?)are carried out before our bags of "shinning white" white rice are placed on sheves.
