It also depends in which direction Poland will go. There will be more and more completion on the market and I wouldn't be so sure that it will be "no problems" in finding a good job that pays well. Unless you have connections of course, which makes the job market in Poland even more difficult for a talented but not very "social" guy.
Yes, I totally agree about the bureaucracy thing in Poland and high taxes. Currently it doesn't make sense to establish a company since in reality most of the money goes not for you, but for the government. Unless you know a good accountant who can help you out (but it's risky...). The best thing, I guess, is to set up a home business and to keep it going "as a hobby" as long as you can; only after you have too much profits to hide, you can set up a formal company. Alternatively, I think it would be even cheaper to set up a company in another European union country and start from there.
Also, learning languages is important, but you are doing great as I can see

. Good for you!
