I know you can't believe everything (anything?) you read on Facebook, but I found these two comments interesting:
Rascal N Dear: Ukraine is already in virtual collapse because of the level of rent-seeking, which has skyrocketed in the last four years and is almost completely being concentrated into the hands of a small group of unbusinesslike individuals (and their proxies, like Serhiy Kurchenko). People are giving up on doing business. Small business has seen over 200,000 entrepreneurs quit in the last few years. That's a disaster for Ukrainians.
Rascal N Dear: Problems began in 2010 when pension contributions were suddenly foisted on sole entrepreneurs, which quintupled the minimum monthly tax rate. Then in January 2012 more changes (three categories with % rates rather than flat taxes) came that drove more of them into the shadow economy. The only source I can offer now is Ukrainian: http://www.bnwes.info/buhgalteriya/arhiv-sayta-2012/sproschenka-za-novimi-pravilami-biznes-yde-v-tin.html
The future for the UK?
