Here in the UK, I get 29 days paid vacation plus ten or so (not sure) public holidays. If I am sick on vacation, I can claim those days as sick days and regain the vacation time. Edit: plus, my contract is for 35 hours per week whereas in the US it was 40.
Regarding money, I am doing the same job that I was doing in the US (same team etc.) but took, what was at the time, a 25% reduction in gross salary. However, by the time you add in the higher taxes, my take home pay (from my salary - my stock awards are the same) is about 40% lower than it was in the US.
Now, I am nearing 50, my corporate career progression is plateauing/settled (by choice, btw) and I have a teenage daughter. A big reason for coming back to Scotland was so she could be educated here and experience European life and culture during her formative years. The other big reason was to have a better work-life balance. I have so much non-work time here, I can actually pursue non-work interests; whereas my US work colleagues seem to always be Slacking and "checking in" while they are on vacation; never seeming to have an identity beyond their job.
I have also lost 13kg (29lb) in weight.
For us techies, the US is the place to get rich, but, in my experience, there are significant lifestyle compromises that you must make in order to do so.
Edit: I was curious about the numbers, so I did a little arithmetic to work out the hourly wage I earned in the US and the hourly wage I earn here in the UK, taking into consideration the vacation days.
My UK gross per hour wage is between 11% and 15% lower than my US salary, depending on the (volatile) exchange rate. Of course, UK tax is much higher (my marginal rate is 49%). So, the difference in take-home pay is more than that.
