When I first started a salaried position in Luxembourg, I took the trouble to check my monthly deductions compared to what I would have paid on the same salary in the UK. To my great surprise, they were nearly identical give or take a fiver!
I am still puzzled as to how that can be - Luxembourg has an absolutely exemplary healthcare system; far, FAR better than the benighted NHS, it has one of the world's most generous state pension schemes (pensions here are contributions related your contribution being a %age of salary but the average state pension is in excess of £800 per WEEK and the absolute minimum for a full career is £442 per week) and benefits are absolutely sky-high compared to the UK. Sick pay is universal and equal to full salary!
So how come the deductions in Luxembourg are at the same level as the UK where you get SFA for your money?
