I can't just imagine it how responsible hard working youth or adults would not be bothered for retirement all because the government would give them cover-up.
Yes, many are bothered because if you have a normal salary, you pay almost half of it to the government. It's true that you get benefits back but 40% is too much to my mind, that really bothers me, especially when I have never used sick leave or visited a hospital since I remember 
But such a system also helps others who desperately need it, so people are fine with it.By the way, even European pension system is a failure and everyone agrees with that, it's not able to provide future generations of retirees with an adequate income, that's why they move in poor countries to live well there because that's not possible locally if you don't have additional source of money.
There are nations with very high tax but a great return, maybe it may not be like that anymore but that is what worse nations were considered as, you pay a huge tax there but you get everything you ask for there as well. The real problem is the nations that both charge a lot but also does nothing, those nations (like USA) are the real problem because why are you even taking the tax if citizens don't see anything back?
