I'm not sure how that "wealthy families" part fits in with this? Maybe this depends on the country, but one example that relates to my original comment was a school which specialized in university students who are about to or just finished their studies and wanted to enhance their studies in a specific area. The whole program was less than a year and the costs would be easily covered even by a few months of part-time work, so we're not talking having to get an actual loan to even attend.
