She’s got her own house, goes to regular spa visits, has been seen negotiating between wildlife and ponies and has a marketable skill set in talking to animals and taming monsters of the Everfree for Ponyville. The hell you talking about “Not having a job?”
She can afford a pretty large house on her own.
It is very likely that the crown considers care of wild creatures to be worthy of funding.
She is an element of harmony and has:
not only undertaken quests for the crown,
not only saved the entire world several times,
but also is currently part of an elite group tasked with being ready at the vibration of a butt to go anywhere :)
Not to mention that she’s an Element of Harmony/members of the League of Friendship in the Crystal Castle whatever you want to call it (forgot to ad that in my comment)
