well yes and no. you actually didnt say anything that disagreed with my comment except the end part. rising costs are a part of life, just as falling costs are, and with things such as food and energy, there are more global causes than anything domestic, though there are certain government policies that exacerbate the problem (specifically subsidies to farmers that grow corn for ethenol instead of consumption),and as of now, most green energy is rather inefficient and is heavily subsidized by the govt, but even these would not change the fact that rising costs are here to stay (though again, somethings are falling in price, such as electronics, but the net outcome is things cost more).

my point is just that inequality is a symptom and an outcome of a more serious problem, and the media tends to spin things from "new global causes as well as domestic policies are making things cost more while a sluggish economy is decreasing wages" to "greedy corporations!"
while inequality is a problem it's not THE problem, again, inequality can rise with wages which makes EVERYONE objectively better off
