Worst French riots in 50 years

Reuters reports:

Workmen cleared away burned hulks of cars, scrubbed the defaced Arc de Triomphe monument and replaced the shattered windows of luxury boutiques in Paris on Sunday after the worst riots in the center of the capital in half a century.

So what has caused these?

Authorities were caught off-guard by the escalation in violence after two weeks of nationwide unrest against fuel taxes and high living costs, known as the “yellow vest” movement after the fluorescent jackets worn by the protesters.

The fuel tax is designed to push people away from motor cars, to lower greenhouse gas emissions. It seems to be rather unpopular.

This graph from Wikipedia shows how unpopular Macron has become. He started with a +20% net approval rating and he now is at -40%.
