Do you feel a profit margin should cater to your specific lifestyle or be something which is standardized between a series of products your company currently offers? When I state specific lifestyle, if you want to purchase a car one month do you raise your prices to reflect the capital needed to purchase the car or do you keep yourself at a level where all products have a consistant profit margin?

I think you are looking at it way too low level.

The goal of any company should be to maximize profit. You charge as much as you can without detering customers. Why would you want to be making less money than you actually could?

That's not always right either.
While high prices can maximize revenue as well as position you as "Luxury" and help with your preceived value, think of: WalMart.

Higher overall profits by doing more sales at a lower cost.

You need to alanize your positioning and perceived sales at a given price point and work from there.
