Speaking as one who has worked for quite a few years in Denmark, in Germany and now in the US, I honestly don’t think I produced any less output from my work in Germany & Denmark, even though I enjoyed the requisite 5-6 weeks of vacation (and do I ever miss those!)
Unless you’re doing mindless assembly line work, there’s simply not a 1-to-1 correlation between “time spent at work” and “useful output produced”. (And even not then.)
The US model - speaking strictly from my own experience with two jobs in corporate America - seems to burn off untold hours on accounting and verifying and quantifying the output of those in the organization who actually do the grunt work. Adding, of course, the requirement of the grunt workers to spend even more time filling out time charts and making status reports, and adding to the organization an extra cohort of middle managers to correlate and massage the numbers. All of this work of course adds to the GDP, but I’m not convinced it makes better (or more) products.
It seems to be a matter of extreme importance to “know the metrics” used to judge your work in order to benefit from the US system. Right now, I should be working on bringing an ailing, overloaded, unstable campus ATM LANE network up to an acceptable level of stability. (Well, right now, I’m at home with a cold. Pity me. Also, if I’m posting gibberish, it’s the fever.) This really should be the focus of my time. Instead, I’m doing cable patches, because a “low turn-around time on trouble tickets” is an important metric for our group - and so, we have to go gunning for the easy ones. I can fix 20 cables in the time it takes to figure out a deeper problem. It produces great metrics for our group and bad service for the company. And my boss as well as I are going nuts over it, but we can’t do a heck of a lot about it.
In Denmark or Germany, the boss wouldn’t use “metrics” as anything but an indicator, if that. He’d be expected to look at the entire operation, see who was doing good work and who was doing badly, see what was important and what wasn’t, and then live up to his manager responsibility by making the calls based on his own judgement, not some spreadsheet.
And don’t assume we were lazy just because we weren’t watched. The 37-hour work week is not for those who want to go places - even in Europe. If there’s a deadline to meet or a service window at 2:00 AM or a customer in Japan, you get cracking. (My first 40-hour-week job in years was here in the US.)
As for the “lack of incentive to succeed” due to taxation, I think it’s severely overstated. The need to self-realize is present or it’s not, and people will strive to succeed - even though the incentives may not be quite as tangible in Euros and cents. Some just want to make something cool (engineers), some want to be top banana (managers), some want to make a name for themselves (entrepeneurs). I sure know a few of all the categories. All of them are making a nice living, too - but that’s not what drove them.
I dunno. Both systems work and the differences aren’t as big as all that. But I sure miss my vacations.
