What traditions would be good to get rid of?

Anyone can break tradition with the norms of their community or society, but which traditions would be good for your community or greater society to drop or at least change in some manner.

There is a recent Q about offensive commercials and one example was diamond rings, and I thought to myself the tradition of diamond engagement rings possibly should be dumped. It’s outdated and asks for young adults to come up with money they should be saving.
