General suffrage in 1789 was about 1 in 20 people, almost entirely white land owning men.
20 years later the vote was actually taken alway from many of the few black men who had it. White men still needed property. In parts of the US this property requirement lasted until the 1850s, and after that the requirement to be rich enough to pay taxes survived well into the 20th century.
