That graph was just showing corporate tax revenue as a percent of GDP. It had nothing to do with effective tax rates on individual companies’ profits.

Taxes alter a firm’s behaviour. They are an expense to firms and to maintain profits they must give lower returns to either workers or investors. Since capital is more mobile than labour, because it is easier for investors to pull out of a country than for workers to emigrate, the burden of higher taxes will fall on workers rather than investors.
70% according to the Congressional Budget Office (International
Burdens of the Corporate Income Tax, 2006.)
