Look, if the top 1% of people used to share 10% of a country's earnings, but now share 20% of a country's earnings, their relative contribution to total tax revenue will grow without any change to the tax regime.
So you need to consider the change in income distribution alongside any change in relative tax contributions. Otherwise the stats you cite are pretty meaningless
Looking at 2007 was a peak in both income earned and taxes paid. Comparing it to today, income earned (as a %) decreased, yet taxes paid (as a % of total) is about the same.
So we can at least say from 2007 to now, tax burden increased.
The tax burden for the top 1% _income_ earners can totally increase while the tax burden for the top 1% wealthy decreases (they earn from dividends, not work)
So you need to consider the change in income distribution alongside any change in relative tax contributions. Otherwise the stats you cite are pretty meaningless
