I may be wildly and incorrectly speculating here, but my immediate assumption about any area with a weak government and a serious corruption and organized crime problem is that starting a successful business is a great way to have a few friendly people (maybe in uniforms, maybe without) show up at your house one day, to explain to you how they are going to be involved in said business. You'd probably find dealing with seven million pages of official Central European paperwork to be preferable to that sort of thing.
