It's less about America "winning" and Europe losing than it is about American corporations getting to fuck over everybody else and American citizens being colateral damage along the rest.
Obama, just like Clinton, adamantly believes that what is good for American corporations is good for America as it increases its geopolitical sway. This couldn't be further from the truth. Bad trade agreements such as the TTIP effectively transfer power from the state and towards corporations, making them even less accountable in some cases.
Edit: let's see what kind of trade deal the UK gets once it leaves the EU.
Well, isn't this what most of the western world has been doing for the last 30 years anyway. Might as well ...
Well, as Funky Papa said, this has been particularly beneficial to American corporations. Just look at share of global profits:
US corporations have at least 40% of global profits in twelve of those twenty five sectors (and two more within three percentage points); not only that but because of the US government's success in influencing other governments to liberalize their financial markets and the ensuing asymmetry of US firms acquiring a larger share of foreign firms than vice-versa:
All told, American firms combined "own 46% of all publicly listed shares of the top 500 corporations in the world," and 41% of all global household financial assets are in North America. This is all great for American corporations, the American investor class, and American power (both a product of and producer of it), but as the article says towards the end:
This is not to say that the United States does not have serious problems, from high inequality and unemployment to sluggish growth. Hence, another insight from critical political economy is that there is no assumption that the continued power of the American investor class correlates with increasing living standards for all.25 Indeed, as mentioned above, the opposite is often true: The more profit the investor class accumulates, the less wages workers receive; hence soaring inequality, as is well-known from Joseph Stiglitz (2012) to Occupy Wall Street26.

Here's a link. I don't know if it'll work for anyone else but worth a try.
