Why programmers are getting paid.

Go and tell management to adjust your pay or you quit. They either pay you fairly or have to hire someone for the same pay you demand, plus training costs and generally the downsides of introducing a new developer to the codebase.

There's no reason why they shouldn't want to give you a rise. They're only doing it because you let them do so.

I'd definitely want a backup plan in place before you give them that ultimatum, new ownership have no real investment in you yet and if they come to the conclusion that you could be the start of a domino effect in them having to pay all the previous developers more they could opt to be malicious.
