When summing up top earners:
- Top 1% of earners paid 24.3% of total income tax.
- Top 5% of earners paid 40.6% of total income tax.
- Top 20% of earners paid 66.4% of total income tax.
Guess their efforts are not that good.
No they are not. But those numbers are also in the link, and it is more or less the same, top 1% earned 20.9% of all income.
Here is another view on the mess of income inequality in the US (with Europe for comparison): https://pbs.twimg.com/media/DjRkWPeU8AIeWtG?format=jpg&name=...
Indefensible really. Digging your own grave.
Again, this is in the source I linked, and if by similar you mean, differing by 14.4%, then sure.
By considering income but not wealth as taxable, the system skews automatically to highly regressive, furthering wealth inequality.
