A normal full time job including holiday is only ~140 hours a month. Assuming you believe their user stats too that would be pretty grim. You probably shouldn’t though.

11 billion engagement hours a month! Does anyone seriously believe that lol. And still not profitable! What do they need, ever human beings every waking hour to spin a profit!?

Yeah, again this is just semantics, a 401k in British English is 100% a pension. A UK defined contribution “workplace pension” is just a tax sheltered retirement account until it is annuitized, which is common and sensible but not necessary. The annuity is technically a totally different product, offered by life insurance companies (who interestingly with reference to above conversation would typically hold very little equity exposure backing it). Brits also call the equivalent to the social security retirement benefit the “state pension”. It’s a catch all for assets you use in retirement. Whether that’s used to fund an investment drawdown product or a life annuity or just taken out and splurged on a Ferrari makes no difference.

About half of the US population is enrolled in a pension even today…

Not true of UK defined contribution, you can do what you want just like a 401k, though it may be disadvantagous for tax purposes.

It’s pretty normal in British English to use pension as a synonym for retirement account, though I can see why you don’t like that.
