Nothing new here. But the key point is that this realisation must be timed / juxtaposed against political and social realities on the groundQuoting from Mu?nchau (emphasis is mine): "In the past two years, there has been a dramatic reversal of public opinion in Germany about the benefits of free global trade in general, and TTIP in particular. In 2014, almost 90 per cent of Germans were in favour of free trade, according to a YouGov poll. That has fallen to 56 per cent. The number of people who reject TTIP outright has risen from 25 per cent to 33 per cent over the same period of time.  These numbers do not suggest that the EU should become protectionist. But… [EU leaders] should be more open-minded about the political costs of this agreement. …A no to TTIP would at least remove one factor behind the surge in anti-EU or anti-globalisation attitudes.

The marginal economic benefits of the agreement are outweighed by the political consequences of its adoption.
