Why does South Africa copy american shows

why do we have to follow these guys when we could come up with our own homegrown ideas for reality tv. there are a lot of shows that are not franchises from USA but you still get the feel of what american sitcom inspired the idea. South Africa has really set a precedent in the states. What huge award winning movie that has any aspect of Africa has lacked anything mzansi. i have seen movies about rwanda with zulu music ..etc . so my question is this ... Do we have to wait for americans to set the pace for us in all regards of our industry? i aint trying to hurt nobody .. it's just an observation and a thought.
