Dress code could have made this list. Conference budget is something I considered, but that also costs out-of-pocket for the firm. I didn't mention benefits for the same cost reason. I've actually had conference costs written into an offer letter a few times for new hires. That is something that benefits the employee and (sometimes) the company, particularly if the company rep is a speaker and represents well. Internal hackathons and 20% (or less) time type programs would attract at least some others.
