No educational institution should institute firm policies preventing students from obtaining an unlimited number of degrees at any level (Associate, Bachelor’s, Master’s, Doctorate, etc). However, private institutions could charge whatever they want for 1st, 2nd and subsequent degrees. Government subsidized institutions should perhaps charge standard rates plus 50% of the subsidized rates for classes required for a 2nd degree (of the same level, for example a 2nd Associate Degree) and charge the unsubsidized, full cost for classes required for a 3rd and subsequent degrees (at the same level).
