In other words, he was incompetent and failed to do his research.
I suppose that what you say is harsh but fair. If people can't be bothered to check what they need to do before leaving a country to avoid having a massive ZUS (and possibly tax) bill presented to them when they go back to that country, that is their own fault really.
A higher bar for starting small businesses is not necessarily a bad thing.
A better method might be an IQ test for prospective business owners, otherwise there's nothing to stop other people's money (for example parents' money) being wasted by wannabee businessmen who really shouldn't be allowed to try to cross a busy street by themselves.
Sorry, I've heard more than enough hard-luck stories by failed businessmen to take their excuses without a huge grain of salt.
Yes, but you must admit that the system here is in many ways so badly set up it's not even funny. For example I have to pay about 40zl more property tax due to running my own business. Each year I need to either go to the post office to collect the registered letter or the gmina office (better choice, shorter queue) to find out exactly how much to pay. I asked this year if I could just add say 50% to this year's amount next year so I wouldn't need to waste my time going to the office. The lady said that I could and they would just send me a registered letter to tell me how much I'd over-paid by....
