It's a hard space to break into. The businesses are conservative about any change, and new vendors are fairly un-trusted. Further, it is a bit different of a world than normal software realms, due to crazy long legacy lifetimes. Another problem is that the money isn't as big as you'd think, its a surprisingly small field.

All that being said, there is opportunity, just not easy opportunity. And a huge number of the people in it are boomers, so there is going to be big shake-ups in the next decade or two.
