The average national rate in Europe is around 18%, and 21% for the EU.
France is competing with this:
Austria 25%, Spain 25%, Netherlands 25%, Italy 24%, Norway 23%, Denmark 22%, Sweden 22%, Portugal 21%, Slovakia 21%, Estonia 20%, Finland 20%, Iceland 20%, Russia 20%, Poland 19%, UK 19%, Czech 19%, Switzerland 18%, Ireland 12.5%
Armenia 20%, Belarus 18%, Ukraine 18%, Romania 16%, Lithuania 15%, Albania 15%, Moldova 12%, Bulgaria 10%, Hungary 9%
Staying up in the 30s would put France at a severe disadvantage vs the rest of the EU and Europe. Germany will also be forced to lower its rate eventually.
The world average was near 40% ~35 year ago. The rate in the US came close to matching with the world average in the late 1980s. After that, the world average began declining consistently while the US remained high. When the world average is 22% and you're at 35%, you have a problem.
