Shared services flights hold ~125 people. If all their flights were full and everyone worked a 2 and 2, there would be ~10,000 positions on the slope. There have been significant layoffs and cut backs in drilling, not to mention ~1/3 of slope workers live out of state, but say 5000 Alaskans work on the slope. Then you have oil field support in Anchorage and somewhat in Fairbanks for spare parts, food services, shipping, engineering, etc. Only a small percentage of people that work in oil either on the slope or in town supporting them are employees of BP or Conoco.

But yes, the government can't wait to punish the productive members of society with heavy taxation.
