Posed question asked: "If you had it your way, what info would every job posting include?", not "What can you realistically expect an employer to share?"

In practice, though, assessing the financial future of an employer before committing your most essential resource, time, is important.

Depends on the country. I work in a secretive company that still discloses lots of financial and personal information, including CEO salary and private addresses of board members because local regulation requires it.
