To be fair, banks go after profits like any other profit seeking corporation in the world because it pleases their shareholders. If you or I owned stocks in BofA, Chase, Citi, VISA or MC, we both will be singing kumbaya because the banks are our friends in making our stock portfolio rise.

That being said, if we all hated DCC fees that much, we could also band together like a "FT consumer union" or so, everyone pitch in $100, and buy a portfolio of BofA, Chase, Citi, VISA or MC stocks and go to their shareholders meetings to try to stop DCC. But frankly, whose stupid enough to buy stock and promote something that will make our stock value drop?
