Yes, foreign direct investment is a poor measure in many regards and using foreign affiliates statistics instead seems very helpful. But referencing controversial Piketty doesn't help in advocating for their policy suggestions. I would have liked to see an exploration of how high-tax countries encourage those differences in "Pre-tax corporate profits (% of compensation of employees)" and how the taxing of individuals has changed in the same time. Germany for example has a progressive income tax capped at 42% yet while incomes rose over the decades, the tax exemption limits did not, effectively reducing the salary needed to reach that cap from 24-times-the-mean-wage two 2-times-the-mean-wage.
