Do not mix the effects of the subsidy inherent in the peg (which are indeed unquestionable) for exporters, with the net effects of the whole policy. So, truly the value of the export worker rises (as you say, and that is unquestionable too), but the value of the non-export worker falls and net employment falls, as I showed in the last post.
Ok, I concede the point. Any purchasing power that is taken to subsidize export work would necessarily have been used for internal consumption otherwise.
