No the fundamental problems was the econmists at the time believe in fixed exchange rates and that's why the got suckered into Bretton woods despite it being a crappy deal, specially for Britain. I didn't help that the American at the meeting was a Soviet spy who wanted to destroy Britain.

And Bretton woods solved nothing at all, it was a system that took a very long to implment, much longer then people think and was unstable almost as soon as it was implemented.
