Which patriot wrote an influential book that denounced british aristocrats as frauds and parasites?

The patriot that wrote an influential book that denounced British aristocrats as frauds and parasites was Thomas Paine, who wrote the Common Sense.

Explanation:

Common sense was an essay written by Thomas Paine. It was published for the first time on January 10, 1776, during the American Revolution.

The essay asserted that the American colonies obtained no compensation from their metropolis, whose sole purpose was to exploit their wealth, and that any sensible analysis would conclude with the need to obtain independence from British rule and establish a republican government of their own.

This work, published anonymously, was an unprecedented editorial success in the United States, managing to sell more than 120,000 copies in the three months following its appearance.
