I know a few (russian) people, working in Russia, either in medium size or in very small businesses.

They all tell the same story : corruption is everywhere, at all levels, and make economic progress impossible. Just trying to work normally is an endless struggle.
They say there is no attempt from the higher powers at fighting it : just some feel-good operations on TV.

They hold Putin and generally the national and local authorities responsible for this state of affairs.
They do not believe this will change any time soon.

So yes, Putin is a failed leader.
