So to survive for a year, I would need 24K of savings. It takes several years to build that up with a normal salary.
To pay for a house or flat, most people work 30 years where I live. And that is with 50K they pay in cash in the beginning - which I don't have, as I don't have rich parents. It takes several years to save 50K with a normal salary. I haven't worked as an employee for a while, but there are taxes to be paid, social insurance, pension plans and what not (mandatory where I live). I think with 60K, maybe < 10K would be left over per year. That's not counting iPads, new Computers, car, whatever (meaning I won't be able to save all that). Also, the pension plan is supposed to be worthless (they've been saying for years that the system will collapse), so I'd have to put some money into a private pension plan.
As a freelancer, I was up to 80K savings in about 3 years (sadly, since then severely reduced, but still).
Yes, you can live comfortably as an employee - as long as you don't lose your job for 40 years.
