More than 100 demonstrators gathered outside Jeff Bezos' Washington, DC, mansion on Thursday and constructed a guillotine outside his front door to protest Amazon workers' wages.

The protest came the day after Bezos' net worth surpassed $200 billion, making him the richest person in history, according to Forbes. His wealth has grown by about $85 billion since January, boosted by Amazon's soaring revenue amid the COVID-19 pandemic.

A video posted to Twitter by a Washington Examiner reporter shows former Amazon warehouse worker Christian Smalls, an outspoken Amazon critic, calling on the company to raise its minimum wage from $15 per hour to $30 per hour in light of Bezos' surging wealth. The protest was led by the Congress of Essential Workers, a group founded by Smalls.

"Give a good reason why we don't deserve a $30 minimum wage when this man makes $4,000 a second," Smalls said.

Smalls was fired from Amazon's Staten Island warehouse after calling for better safety standards amid the pandemic. He said he was fired as retaliation for organizing a walkout after an employee tested positive for the coronavirus, but Amazon denied this.

Since then, he has led multiple protests targeting Amazon and Bezos, including an August 10 protest outside Bezos' New York apartment building.

While the COVID-19 pandemic has prompted some Amazon employees to speak out about working conditions, it's also been a financial boon for the company. It reported $88.9 billion in sales in the second quarter of 2020, a record for the company.

It's not clear whether the protesters' guillotine had a real blade or was functional. The Congress of Essential Workers did not immediately respond to Business Insider's request for comment.
