What is the main conflict in A Thousand Clowns by Herb Gardner?

The play tells the story of Murray Burns, a cheerful eccentric raising his nephew, a twelve-year-old genius, in New York City. Murray believes in living life fully, even if that means going to the movies instead of looking for a job. When social workers from the Bureau of Child Welfare come to investigate, he must decide whether to accept some level of conformity in order to show himself a fit guardian.
