As I responded to a previous question, there are two elements to getting demand and supply in balance: supply and demand. Demand is well above supply. The more supply comes up, the less demand will need to come down. Given that any actions taken on supply will take time, and that the economy is clearly in excess demand, there is a need to slow demand. From a monetary policy point of view, the tool we have affects demand, not supply.
Yes, the more governments and parliamentarians take actions that augment the supply side of the economy, the more room there is for the economy to grow without inflation.
