There's always more of these Corbynite goons, isn't there? This chap is Young Labour International Officer.
1) Macron isn't "privatizing trains". He's trying to get the hugely indebted SNCF into shape where it can face up to competition that's mandated from 2023. Italy, by the way, already has privatized trains running and the nationalized operator welcomes them as helping improve their own performance.
2) The CGT are a minority trade union body, of whom there's no equivalent in the UK.
3) "Reform agenda" means having an actual plan to reduce long term debt. France has one that addresses its weakenesses, like 30 years of high unemployment, Italy is handing out a lot more money to pensioners while its young leave.
4) The reason France has a deficit of 3.2% is that an unholy alliance (not least the CGT) went apeshit at petrol taxes going up and its hard to replace that income.
5) France's debt is way, way lower than Italy, and its debt interest costs about a quarter.
6) The UK isn't in the Euro, so it's not going to have any of the same tests.
