In 1890, the wealthiest 1% of Americans owned one-fourth of the nation’s assets. The top 10% owned over seventy percent of those assets. By 1900, the richest 10% controlled approximately 90% of the nation’s wealth.
Those are some high numbers! But this will lead to power instability in society since the richest people holds the majority of the country's wealth, meaning they get to make the majority of the decisions, and the voice of the people won't be heard.
