End of last month I attended my Maori tribe's governing body's AGM. Reading between the lines, what I liked about their approach to business is a departure from "hire your own" to hire the best and train your own. In the last, a lot of tribes took grant money and gave jobs to their own believing that their own blood would not do them wrong: but they lost through fraud and/or incompetence. That old insular thing of hiring your own makes it incumbent on the tribe to ensure members are competent. That's just not possible in today's complex world imo.
But, it's a complex issue to mediate through retaining cultural values in a changing world. I hope they don't leave it too late - they live in a beautiful part of the world.
