Human Nature?

I am watching this documentary called "the cove" which asks the question about how moral it is to keep sea mammals in captivity? But what about us land roaming humans? Are we as humans doomed to stay in the vicious cycle of metaphorical captivity of financial nets and social tricks? Do we need someone to release us from these confines and lets us roam free in the wild like we are meant to? While watching this documentary I began to see the juxtaposition of both worlds and how similarly related they both are.
Some sea mammals such as dolphins get trapped in coves which are meant to capture them, and during the struggle to free themselves the dolphins drown in these man made contraptions. Sometimes I feel as though the class system is set up in such a similar way. Society tends to keep down the less fortunate or lower classes by keeping them in their said class. For example, there are fewer tax breaks for the lower and middle classes; also, the quality of living is less because of the forced diet of high fructose corn syrup and cheaply enriched/ bleached grains, which causes various diseases such as, diabetes and high blood pressure. In turn the pharmaceutical companies make their money off these poor people who can not afford the recommended nutritional foods because of expense of these foods, which are high vitamin and mineral value. Therefore, health insurance rates rise and the cost to cover someone becomes almost too costly. An thus, the vicious cycle of these class controls continue and until we can make a stand against these economic trends of keeping the rich healthy and ridding the poor with disease.
