I have always assumed that Malivina intended the song - words and melody - to be in the form of a children's song, so yes it is a simplistic trite melody with simple words. Basically asking non adults (or others who have not yet achieved "success") is this what you really dream to achieve - in a pointed way that is admittedly critical of those who had achieved it. To me the song is dated and doesn't hold up that well but not overly offensive. It criticizes what some people felt was middle class success. Probably could have been done more subtly but in the 60s we often criticized other people's life choices - in speech or in song - quite directly. Is there really something wrong with songs that are critical of other people?
