In the beginning (or close enough to count as the beginning) there were four ways to make ISK in Eve: miners who extracted wealth from asteroids, manufacturers who took those raw resources and built things to sell to other players, missioners/ratters who killed NPCs for profit, and traders who played the markets to create ISK from the complexities of the orders.
As corporations formed the question that arose was how to make ISK from the members of said corps. For miners and industrialists and traders, and corporation made for those activities had the implied necessities of cooperation and leveraging different abilities (e.g. miner versus hauler versus refiner) such that it makes sense to pay into the corporation to get something out of it you cannot do yourself (and this is back in the day before alt character proliferation, mind you).
But with NPC killing, the bounties are paid directly to the wallet of the combat pilot whether you are in a belt or mission. Cooperation helps with these activities to a point, but they are not impossible without other combat pilots (prior to salvaging of course). To address this imbalance corporations were granted the ability to tax payouts from agents and CONCORD to players in the corporation. And all was good.
But the game has changed since then and changed a lot.
Somewhere along the line CCP economists realized that direct ISK payouts increased the ISK supply and helped increase inflation. To combat this, the concept of rewarding players with a new mechanic called Loyalty Points was created which allowed players to receive rewards while creating an ISK sink as opposed to faucet. At first they were used to augment rewards in missions and then were used to replace ISK rewards in many new features such as Faction Warfare and Incursions.
The problem is that corporations that exist in these areas now have no corporate income from the day to day activities of member pilots, and are forced to look at top down income sources (i.e. moons) or micromanaging some sort of manual levy on pilots or surviving on donations.
Its time for CCP developers to put their heads together and come up with a plan to allow corporations alternative methods of taxation. At the very least, I'd suggest apply taxes to Loyalty Point gains, and I'd even consider taxing market transactions and contracts.
