Running the numbers:
1. Economists are not created equal. Mathematical econometricians are paid at the same level or higher than entry level pharmacists, even at the BS level. If you happen to be an qualified actuary, add 20% to that. However, for macro, international, or any of those poet concentrations, expect to make nothing.
2. Pharmacists are (generally) created equal. Expect a new grad to make roughly the same as you in the same job. (To all you Kroger/Rite Aid/Target/CHW pharmacists, I realize that is oversimplification, but it's generally true). That's not bad, because we are paid pretty damn well, and the job market is healthy even for the economy even if the HRSA worst-case labor scenario plays out. As a comparison for our salary inflation from 1990 to 2010, look at this:

compared with the current salary structure. We're doing very well.
3. Job security: Pharmacists do enjoy a large level of job security through the inelastic labor supply. Economists don't have that protections. Strict MBA's don't unless they are also actuarians or accountants (you can't sign either of those reports on a legal basis unless you qualify). Read Arrow for details. Economists don't, in fact, I was put in a mathematical economist position for six months (no economics knowledge but math skills at the Complex Analysis level) because it paid better than pharmacy until I was brought on as a researcher. I certainly displaced another economist who had formal training. What made the difference was for the project that I was assigned to, being a pharmacist who could understand the business and project forecasts in that context was more important.
4. If you want to be a management consultant, by all means complete your PharmD. Pharmacists are real hard to come by at the
Big 3 and are paid handsomely when that expertise comes around. Sorry to make an ad hominem comment, but from what you've written, your ability to get along with clients may be lacking.
5. Also based on your knowledge, consider training in informatics, supply-chain management, or quant. finance. There is a place for someone who is facile with this sort of knowledge in pharmacy at that level, certainly at the national distribution level.
