Translation of above image:
The Top 1% of wage earners (those earning over $380,354) pay 38% of all individual Federal Taxes.
The Top 5% of wage earners (those earning over $159,619) pay 59% of all individual Federal Taxes.
The Bottom 50% of wage earners (those earning under $33,048) pay only 3% of all individual Federal Taxes.
For historical perspective, back in 1986, the top 1% of earners reported 11% of all income and paid 26% of the income taxes; the lower-earning 50% made 17% of the income and paid 6% of the nation’s individual income tax bill.
