Europeans can have the luxury of not worrying about investing since many European countries offer livable pensions (for now…the demographic future for this isn’t looking so good).
However, this isn’t as great as it sounds. While the European model for healthcare and education is better, their pension schemes are arguably a much worse deal than what Americans can have.
In Europe, you’re basically paying the government to take your money and invest it in much too conservative, in fact, negative-yielding! bonds right now due to pension fund mandates.
You can’t take the proper amount of risk given your age (in your 20s-40s you should be almost fully allocated to stocks) because the pension fund needs to constantly be paying out money to old people—they can’t risk huge drawdowns.
There’s a surprisingly large amount of middle class Americans who will retire millionaires just because they are able to save for their pension privately and take the proper amount of risk for their age (eg. Target date funds).
Meanwhile, in Europe, governments shelter people from the harsh realities of how financial markets work, but you have to hope and pray that enough people are born in the coming decades to make up for the conservative pension mandates. And you have to pray that the government allows you to retire sometime before you die (in the nordics, retirement ages are constantly being pushed back and pension benefits are shrinking...due to said demographics).
I predict every country will eventually move to a hybrid private/public pension model like the US over the next 40 years. So you'll have to start caring eventually.
