From the Wikipedia on the Gilded Age:
- The top 10% owned roughly three-quarters (75%) of the nation's wealth.
- From 1860 to 1900, the wealthiest 2% of American households owned more than a third (33%) of the nation's wealth.
- The bottom 40% had no wealth at all.
- In the third quarter of 2021, the share of net wealth held by the top 10 percent is 69.6%.
- The share of the top one percent net wealth is 32.1%.
- The bottom 50% in the US hold 2% of the nation's net wealth.
And this isn't even including the comparison of monopolies from then to now.
This massive inequality precipitated serious societal upheavals in the US in the early 20th century.
