What's your beef? Ballet dancers getting a pension at 40? How many ballet dancers are there in Poland? Big deal, not enough to worry about. Poland can afford it and it can afford to offer a safety net to the poor and old.
Poland can't afford it, this is the thing. Constitutionally, Poland is riding extremely close to the edge - and if it reaches the edge, we'll see massive cuts made. Why should there be exceptions for people just because they choose to do a career that is physically demanding? Professional sports people don't get to retire early, so why should dancers?
As for the safety net for the poor and old - no-one wants to cut their net, but we want them to work for it. And we're exposing the sheer stupidity of using today's money to pay for pensions earnt in worthless Communist Zloty.
How many ballet dancers actually have a major career as a full-time professional dancer into their 40's? I'd suggest not that many.
Well, if they are around until they're 40, I'd be all for giving them money to retrain. Many of them missed out on an education, so they should get funded to go to university/etc. They'll have a good 25 years of productivity left - why the hell should they get to retire at that age, only to end up (in most cases) working illegally anyway?
The only reason that the pension system hasn't completely collapsed is because payments are not being increased at the rate of inflation. It's less money that has to be spread around, but a huge burden on workers and employers. Workers because it takes quite a bit of their earnings, and employers because it makes the cost of employing labor quite a bit higher, with all the negative side effects of that.
It's a huge burden and is almost certainly the reason why many Poles don't have ZUS paid as part of their employment.
