When we get a new government, taxing organisations like Amazon and Ebay should be high on the agenda. They claim to be based elsewhere (low corporation tax jurisdictions like Ireland) but they are sucking up huge amounts of UK retail business and need to be taxed fairly.
Unlike individuals, mega profitable corporations will not jump on a plane and go elsewhere. They won't turn their back on profitable markets.
Mind you - be clear about this. It won't be Apple, Ebay, or Amazon shareholders who pay any tax. They will simply raise the prices customers pay. Corporations don't pay tax - their customers do. So when you tax Ebay, you pay when you buy something on the platform.
