I have an electric stream behind my house. Water flows down the rocks, offering a drinking fountain for the dog, birds and wasps that live here, and soothing sound for me. There is a pump submerged at the bottom of the stream to raise the water back to the top. Even with the pump running, I must regularly add water to replace what the critters and the sun take from the system during the day.
Money, I’ve noticed, is like my backyard stream, in reverse. Money naturally flows uphill.
