Really? You don't want Facebook to pay tax?
Macron is no angel, he is more or less despised by French citizens for his increasingly authoritarian government. And 3% is nothing even as a revenue tax. I'd suggest to check the worldwide profit margin (i.e. add in all the revenues reported in tax shelters) of these multinational tech companies and then work out what 30% of that would be in a revenue tax. Or 99% (of actual profit) if you want to fund climate change resilience (public transport, moving from coast, closing down big coal and oil). Actually I'm not even sure they deserve 1%. Also include all the other multi-national tax avoiders.
