Does anybody know why in the world ....

There were 180 episods of the golden girls filmed. Does anyone know why "we" seems to think that the desission they've made to show only the same 30-40 episods over and over and over and over and over again is the best desission???? 180 episods! Yet only the same ones .... Over and over and over and over .... Lol. WHY?!
