And don't forget that 'payment processing' is never free. In fact, it is never even a flat fee despite the fact that it does not actually cost anything more to transfer a larger number over a network than it does a smaller one. Yet people seem to have no problem handing over the majority of their economy to 'processed' payments which empower banks with the ability to do nothing less than levy taxes and exert the same sort of control over the economy that was previously reserved to the federal government. If they wish to restrict the availability of money in the economy, they can simply raise the payment processing fees. If they wish to boost their own profit margin, they simply raise the payment processing fees. They show favoritism by giving large companies big discounts on those fees, revealing them not to be fees actually needed to pay for a service being provided but merely a chunk of money they take simply because they can.
