“ Negotiated Rates (NSA) can allows companies such as Amazon to buy postage at a significant discount. These deals should be eliminated. Why should a poor person pay more for postage than Jeff Bezos to ship the same thing?“

Rather than suggest that Jeff Bezos gets a deal on postage due to his influence, perhaps a better characterization is that the American consumer enjoys the efficiencies of bulk purchasing power, essentially arranged on our behalf by Amazon, which lowers our shipping costs. Bezos doesn’t get cheaper postage than we do; we buy things off amazon and win.
