The Ottomans have been gone for less time than the US has been free of slavery. African Americans, as a group, are still struggling. I don't see why an entire nation should be recovered.
Comparing Bulgarians 200 years ago to african slaves in Usa is quite weird. Blaming Ottomans for the todays Bulgaria's all problems is beyond ridiculous, and maybe the sign of the real problem.
Would you prefer a comparison to Haiti, which gained independence 100 years before Bulgaria?
Did Bulgaria have huge indemnity to pay like Haiti?
