I think the thought helps them sleep at night.Many Americans are oblivious to the suffering other people throughout the world must endure for Americans to be #1.
Capitalism is evil if not countered with strong socialism.
The products we buy, the choices we make as consumers has a direct impact on the suffering of others, when we demand low prices, we also demand someones else's suffering.
Maybe if Americans could tour the sweat shops of China, South America, India...maybe their lust for low prices would wain.
Consider that since 1962, federal revenue from progressive taxes (in which higher income people pay a higher tax percentage than lower income) dropped by 17%. Federal income from regressive taxes (which place a higher burden on those with lower income) increased by 135%. Since 1980, taxes on inheritance and investment have dropped by 31% while taxes on income derived from work have increased by 25%. Between 2000 and 2003, corporations (the institutions that perpetuate and insulate the plutocracy) saw their contribution to federal revenue through taxes fall by 36%.
EDIT; See the negative thumbs on my answer, therein lies what is wrong with America today.
When we accept the mythology that hard work will make us wealthy just like the ruling elite we embrace wannabeism. We want to be like the wealthy. We want to support the rich ruling elite and the powerful, not because it is in our own best interest, rather, because we want to be like them. Perhaps, the thinking goes, if Ms. Mornin only had five jobs instead of just three, she could join the rich club alongside the Bushs, Kennedys, Kerrys, Guilianis, Saudis, etc., of the world. While the working class is duped into struggling to be like the rich, power is passed on from generation to generation via inherited wealth. Sons are given access to the best schools, given companies to play with, bailed out when misdeeds are committed and transgressions expunged. Being wealthy means never having to take responsibility. Being part of the elite means never having to say you're sorry. Being born into wealth means never having to do either.
