I'm not sure of the details of Spain's proposal but something needs to be done really to make taxation more fair. At the moment you get headlines like "Facebook paid just £28m tax after record £1.6bn revenues in UK" because they fiddle it with offshore tax havens while normal UK businesses have to pay more like 30% of their income in tax, not 1.7%.

This conflates a few things. As I'm an American, I'm going to speak about US tax law, but concept should be applicable. No normal US business is paying taxes on their _revenues_, they're paying taxes on their earnings…
You'd have lost $1B. You'd have to sell 2B $1 bills @ $0.50 to make $1B revenue.
