Because you get to work as a tech consultant fixing sf issues and extending SF for the many many corporate customers that use it. There are whole agencies built around doing SF implementations and other SF work and there is plenty of money to be made in this space. I know people at Deloitte that went from SF consultant to director and even one to partner. Plenty of devs work with specific products as these products are used by many companies. I know lots of ERP developers that make very good money scripting customisations into ERP systems, it's a pain of a system but you're right at the heart of the business working on very high value contracts.
