I’d encourage thinking not just about yourself or your immediate circle when it comes to policy like retirement age. State run pension systems affect nearly everyone, not just the extremely fortunate few who can become financially independent at a younger age. And that is also largely an American phenomenon anyway. Salaries are much lower on average than in Europe and there is far less differential between minimum wage and what senior employees get paid. There’s also not the same culture of investing because European companies don’t have the same performance as the US stock market. Lower yield real estate investment is much more common in many European countries. And with strong social safety nets Europeans are generally less pressured to save a huge nest egg.

So this raising of the retirement age will affect a huge portion of workers and 70 is OLD to be working full time for all but the most relaxed jobs. Most older folks I know have know being dealing with multiple chronic age related illnesses well before 70.

well in this context it generally means the age someone starts to receive state pension.

How does this make huge sense?

It's a financial goal that is literally based on how long you plan to live, aka, your age.

Let's say I have €100.000 in the bank and that's two years of expenses based on my budget. Can I retire tomorrow? Well, what's my age? and what X do I plan to add to my age to determine if that amount of money is sufficient to retire?
