If an economy consists of a butcher and a baker and nobody else, low interest rates may allow either of these business owners to expand their operation, but that's it. Maybe the butcher can produce 20% more meat and the baker can produce 20% more bread, but if the demand for meat and bread doesn't change then the GDP of this economy will not grow.
Your post is ridiculous. Low interest are key to economic growth and Trumps political survival. Their only down side is is inflation ( no sigh of that) and some old people end up eating dog food. Ha ha.
