>>13001862Interest is only bearable by profitable endeavours, if nothing can make more than 3% net profit that bankers can't take more than that in interest. We can see than that the interest rate will be close to the average rate of profitability. In someways the interest rate is reflective of the low hanging fruit being picked, and that any energy efficiency gains being made are being met with an equal and opposite increase to the price of energy, the limits of post industrialization.
non-scientifically speaking this is why I advocate infrastructure programs that increase the average rate of profit. Things like De-icing the northwest passage and picking up 20% efficiency gains in trade between China and the Atlantic coasts
