The shipping industry is well overdue for disruption. I never understood why it costs more to move something than to make something. With that said, with some planning you can keep international shipping cost to 15% of your invoice. It costs $65 to ship a $100 item from U.S. to New Zealand, but you can quite easily ship $1000 worth of goods for $150.
Like any other big business, when they start, like Fed Ex , it is usually pretty good cost wise. As they accumulate hierarchy and liabilities, it becomes a battle for survival. Look at USPS, overburdened with unfunded liabilities and they are really getting "bailed out" by taxpayers.
You are correct they are in need of disruption.
