The billionaire's club just got starrier. This Wednesday, Forbes revealed Rihanna has amassed a fortune of $1.7bn.

Robyn Rihanna Fenty's life is extraordinary. The now 33-year old singer grew up in Barbados, where she sold clothes at a market.

She was discovered in 2003 by a visiting record producer, who invited her to the US to record demos. Soon, she was signed to Def Jam by Jay-Z. What followed was an 11 year streak of hits, with 31 US top ten singles and 14 No. 1s.

The bulk of Rihanna's fortune, however, comes from her cosmetic label Fenty Beauty. Launched in 2007, it has made headlines for catering to a huge variety of skin tones.

Rihanna has long been generous with her wealth. In 2006, she founded the Believe Foundation for terminally-ill children. Six years later, she opened the Clara Lionel Foundation, which supports global education and climate change resilience. Last year she donated $5m to Covid-19 relief, $2.1m for victims of domestic violence and $700,000 for ventilators in Barbados.

Rihanna's behaviour contrasts with a view that wealth corrupts.

Today, society tolerates, even celebrates, extreme wealth. From adventure-lover Richard BransonHis businesses have included Virgin Records, Virgin Trains and the space-tourism company Virgin Galactic. to the philanthropic Microsoft founder Bill Gates, plutocrats have become celebrities.

This might be a symptom of capitalism, the economic system followed by much of the world. Capitalism stipulates that wealth is owned by individuals and companies. It seeks wealth as a sort of virtue in itself, which everyone should aspire to.

Many have disputed this. Karl MarxA 19th-Century German economist and philosopher who argued that capitalism was doomed to collapse. believed that inequality would drive people to form a socialist society, where wealth is controlled by the state and shared equally.

Socialism has been marginalised in many Western countries. But a belief that billionaires harm society rather than help it, is growing.

Two DemocraticA democratic election is one where all eligible citizens are free to vote, where votes are counted fairly and all political parties have fair and free access to communicate with voters. candidates for the 2020 US election, Bernie Sanders and Elizabeth Warren, called for a wealth tax on the ultra-rich.

Even the very existence of billionaires underlines the world's inequality. A 2020 study found it would take $330bn to end world hunger. Strip the world's two richest men of their wealth, and you would be just $2bn off making life immeasurably better for billions.

Is it possible to combine virtue with insane wealth?

Filthy lucre

Yes. Everyone can perform virtuous deeds. The ultra-rich have the ability to do good on an enormous scale - and they often do, as the numerous foundations, institutions and funds in their names prove. Besides, without the wealth generated by society's most successful, there would be less money to filter to good causes.

No. The very existence of the ultra-wealthy is a kick in the teeth to the notion that humans are equal. That Jeff Bezos can take a private rocket to space while Amazon workers toil in dreadful conditions should disgust everyone. When the rich do give, they do so to promote themselves while doing little to address larger inequities.
