Causation versus correlatooncorrelation
I wonder about your example on water supply via private or public entities. You relate improvements in England > Wales > Scotland > NI to privatization. But if I am not mistaken the former had growing economies and populations and the latter had less of that. Maybe your numbers just show that investment occurs in growing regions?
Is here any indication about causation in this or other examples of privatization? Or is it just wool over all our eyes?
