Europeans are delusional about pensions and retirement. The whole system is predicated on the fact that people with ill health forced to work is a danger to themselves and others. It's not a medal or reward for managing to hang in there. Since medical research and just healthy lifestyles allows people to live a healthy life far beyond just half a century ago. Not only being alive. But being healthy.
Europeans seem to think it's some sort of basic human right to fuck around in their 60'ies and live a jet set life. It's bizarre. Especially for (I think) all European countries where pensions are paid for by the state. All European countries is inexorably being pushed toward a situation where a low pension age causes economic crisis.
The IT boom following from the 1980's until now has made us, comparatively, mega wealthy to earlier generations. An hours work today generates as much purchasing powers as six hours in 1970. That's a crazy high difference. That means we're now accustomed to a much higher quality of life. To maintain that quality of life, we need to work longer. Basically, removing people from the workforce is much more expensive now than it was in the 1970'ies when the current rules were put in place.
The calculus is this, either we accept a worse standard of living and continue with these low pension ages, or we keep our standard of living and raise the age of pension.
Politicians all over Europe are trying to find ways to talk people into seeing reason. But we (European voters) have our head in the sand and just refuse to see reason.
Macron is just doing what needs to be done. The problem is that he's using draconic measures to do so. Article 49 of the French Constitution is a tool intended to be used to break a deadlock in the government. Not intended to force through unpopular measures. That's abusing the power. It can be compared to the US presidential executive order. Obama was allowed to use it to force through Obamacare. But it was a violation of the intent of the law.
