Emotional security can be an asset in getting another job or in obtaining money or material things. But being abused is crippling and will not get you anything worthwhile.
I am in this sort of situation right now. And I have chosen early retirement and being broke.
I've been through both extremes. It's nice to have a comfortable environment to work in. If your boss is abusive, you are probably having your self esteem shredded on a regular basis. Possibly you are being paid higher so that you would not leave as all the others have. Determine what you would be comfortable making do without. And if you can live with it.....perhaps it wouldn't be so bad changing to another job. Or else have a heart to heart talk to your boss about the way he treats you. If he doesn't make an effort to change....look around for a better job.
