A remote tower with pooled ATC has to be the way to go for smaller airports with few scheduled movements. Off the top of my head, places like MME, CAX, CAL, HUY etc. might benefit. It is quite reasonable for ATC officers to be properly paid and to have a proper career, but airfields like these can offer little other than being nice places to live. But a good career coupled with a superb location to live could created for ATCO's who want to work in this part of the industry. At the same time these airfields would get proper ATC at a reasonable price.
