I don't think they can stop the 3 things you mentioned though.
- Stopping R&D means their top engineers and scientists will go elsewhere
- Stopping marketing means they will slowly lose market share. I don't care for marketing personally but I can appreciate its importance in a corporation
- Stopping/reducing compensation will also make them lose people
The costs are an inherent part of the company. It can't exist without it. Sure, they can adjust some levers a little bit here and there, but not too much or it all comes crumbling down.
