The Bank exists to help the state and its businesses function well and to maintain liquidity and economic stability. BND created the infrastructure for North Dakota’s oil boom, and if the state were to commit to a truly proactive transition to renewable and clean energy (it has taken baby steps), the BND would make it happen financially–with an efficiency that would put the rest of the country to shame.
But in the present political reality, cops and soldiers are brutally cracking down on Standing Rock protesters, and BND is funding it, and that makes BND not truly apolitical, but a facilitator of injustice. Public banks are tools, not sources of virtue in themselves. In the hands of bad policymakers, they can prop up bad policies.
