It's not that they don't care about money it's that they are less affected by loss.
Once someone earns about 10 million they can live for the rest of their life in a reasonable way without working again. So when you are an executive who has assets of 50 to 70 million and your stock, which was worth 10 mil is now worth 7 mil you aren't hurt that bad.
The company can they raise prices, cut quality, and fire people to reduce costs to make up for the fine. The stock might eventually even go higher than it was before.
