The truth is, your manager's goals are probably more aligned with yours than either of your realize. Part of growing in your career is learning how to make the connection for other people between these unintuitive things that make development faster and the goals they are trying to achieve. I wouldn't give up on finding new ways to share that understanding. It's called working on your leadership skills.
I'll caveat that there are some cases where it doesn't make sense to do the things you described. Maybe you're working on a prototype, or maybe the cash situation of the business is truly precarious. But if you want people to buy in on change, you need to understand their goals and relate to them on that level. Good luck!
