I thought you knew better what the political scene in Poland had been and that it had not been the case of Poles hating and doing damage to fellow Poles. Of course, you will find sell-out Polish (meaning, of Polish nationality) scumbags among so-called Polish government and rulers here and there too. We are capable of ruling ourselves and well, from central to local government down, but it doesn't happen full-scale until the current mess (including the people responsible for it) is cleaned.
We've got a saying that sort of refers to our internal relations you describe: it's "Polak Polakowi wilkiem" and interestingly, it seems it has been mostly brought up in external context, when we are abroad and refer to situations that happen there (more, it usually has got to do with professional situations and about). However, I don't know where it's come from and, more importantly, why it's generally stuck. Sure, there occur bad feelings, disagreements etc. but from my (I've travelled and stayed some in Europe and the US) and my relatives (who live across Europe and the US) experience and observations it isn't like we're brutish and hateful against each other at all. Our organised, active diasporas ("Polonia") on practically six continents are another thing that confirms that.
Before, the problem in Poland and a host of other European countries was that people were sometimes retiring at the age of 50-something. Any health impairment was able to be inflated to the level of a full disability with the friendship of the right doctor. That was wrong. I am 51, not in the best of health & I work full-time, including overtime. My birth year, 1961, obligates me to work to age 67, while those a few years younger than I can retire at 65. My son, born in 1996, is expected to reach retirement at 71 and my daughter, born in 2001, at 72. So, stop moaning & get to work.
