There's no vacation/holidays/sick leave included because those hours that you actually don't work are still paid. In other words the vacation and holiday policy is just a discount you get from your employer on the total 2080 hours per year they would have otherwise requested from you.
Um, the average American worker gets 10 days of vacation a year and many get far less than that.
Many many many Americans work holidays too, I just worked my 13th Thanksgiving in a row.
2080 divided by 37.5 is about 55 weeks, while there is only 52 weeks in a year. If you count it as 40 hrs per week then it is 52 weeks but people usually don't count the extra half hour which is usually a break but that could be your number.
This is probably a better comparison to the korean number for the US: https://www.fool.com/careers/2017/12/17/heres-how-many-hours...
How did you get that? When I was an hourly employee, my shifts were 8.5/9 hours clock-in to clock-out, to allow for a 30 minute or 1 hour lunch break.

I've never had a non-retail job with paid breaks. I work 40 hours a week, minimum, with my 30 minute lunch off the clock.

As a South Korean, my impression is that full-time workers in desirable positions tend to put in around 2,500 hours per year. We recently introduced a new law that puts a hard limit (for any given pair of employer and employee) of 52 hours per week, averaged over a 3-month period. There's been a lot of pushback from businesses that either require or encourage working even more hours.
