This is a bit outdated. Most mafia bosses have been long dead.
As for the corruption it depends much on the place, scale, else. Officials get prosecuted. Practicing petty corruption (on the road, passing a unversity exam) has become dangerous though still exists. Purchasing something for the government at a double retail price receiving the difference as a bundle afterwards has too. The Putin’s friends do have a priority with the government contratcs, but there are not so many of them. But you can never win a lawsuit against a government agency. Sanitary or fire inspections have become less frequent, and probably, fullfilling the regulations is a good idea. Many government services have become available online, though the quality of the regulation is generally quite poor.
You are mostly right although poor public services are mostly a result of a small government.
As for inability to beat the government at court is is a rather widespread belief but it isn’t actually supported by facts.
The problem is most people do not seek quality legal advise which is actually available but not cheap. There are lawyers specializing in it and due to overall low level of government employees your chances to beat a thing like unlawful fine or another administrative act is actually higher than elsewhere.
