Carriers have the choice to say yes, or to say no to whatever rate is offered. Depending on fleet size, specific lane, re-positioning, etc. ,someone could say yes to a rate that others might find low. This idea that brokers somehow control freight rates similar to how the large fuel companies control fuel rates is ridiculous. The moment a carrier agrees to a rate, high or low, that rate can be used as the new standard going forward. Have we all forgotten what rates were doing earlier this year and late last year? Floods in BC, no trucks available anywhere, rates at 5, 7, 10++++ dollars a mile???? I don't seem to remember much grousing about low rates and brokers gouging carriers then. In order to survive in this business, you have to accept the fact that rates will always fluctuate, establish mutually beneficial relationships, learn to not panic and say "no" when you have to, and most importantly, know what your costs are inside and out, upside and down. Without that knowledge, all the other suggestions are meaningless.
