With ISK, supply chains can be implemented and machines can be created. Machines of destruction can help when diplomacy has failed. War is an extension of diplomacy. Machines of creation keep the supply chains operational. The balance of creation and destruction must tilt in favor of creation or New Eden will vanish.
Train to build efficiently and timely. Build good stuff that Capsuleers use and build stuff that supports your efforts, usually both goals will be in alignment and provide good ISK flow via proper marketing.
Do not let dick-head Capsuleers get you down. They are out there and just know New Eden has not collapsed due to their ignorance. There are forces trying to destroy New Eden and always go back to equation of Creation greater than Destruction and there you will find stability. Without adept Creation, New Eden would collapse.
