These exact same words could come out of a Brazilian. Word by word. I don't know about Croatia, but in that case they are only half-truths. The idea that there are 'people who pay for everything' is usually misguided. There are the exploited, and the less exploited. Both pay in one way or another, and only a very small elite group is actually well off.
You say "the situation is complicated" and "this is not fair", but how exactly do you think this measure will fail? From a distance it sounds like it would boost the economy by allowing people to prosper, while debt is written off mostly by private entities, not the tax payers directly. Even if it was, it might still be a win.
