revised How can access to curated data needed by GeoRegionValuePlot be speeded up?
Rephrase the question to make it clearer that it is the GeoRegionValuePlot what needs to be improved.

comment How can access to curated data needed by GeoRegionValuePlot be speeded up?
@Hans, thanks for the answer and comment. I may have to rewrite the question.The issue is not pulling the data itself, but processing the GeoRegionValuePlot. Wanted to use the manipulate function to zoom to specific continents or country groups. The function takes a long time to process. I'll update the question.

Dear @KellenMyers. You've been duped by the "flaw of averages".hbr.org/2002/11/the-flaw-of-averages/ar/1 . Working with averages might make you take an incorrect decision. If instead of averages you work with Stochastic Variables, you would observe that the solution you would chose would be quite different. Some cartoons for your amusement (danielvaverka.com/the-flaw-of-averages)

Brilliant! Dataset[AssociationThread[Drop[fields, {5}], #] & /@sales[ GroupBy[{#Country, #Region, #BU, #Year} & -> Key["Sales"]] ][Normal, Total ][All, Apply[Append]]//Normal] puts the keys back again. ]

comment Finding maximum/minimum value of system of inequalites
Kadir, you are missing the function you want to maximize in the Command. Format should be Maximize[{function,constraints},{x1,x2}]. For example Maximize[{x1+x2,your_Constraints},{x1,x2}]
