Re: Well, duh
"Since Frankfurt, Paris and Dublin have already picked up a good deal of the financial markets business "
They really haven't. Financial institutions have mostly opened tiny satellite offices in the EU with a skeleton staff so they can make local executions where needed. The vast majority of people who matter are staying put. After all if you have ever visited Frankfurt you would realise that next to no one wants to move there. And no trader wants to pay French taxes.
