No. You grow the economy by adding value. Birth a child...you've added value (usually). Create a product...you've added value (usually).
Become more efficient...you've added value (usually). Become more productive...you've added value (usually).
Increase the multiplier of money transactions...you've added value (always). This is why increasing the speed of money is so important.
So look for solutions that add value to our economy. What will make us create more products, become more efficient and more productive, increase the speed of money, etc?!
HINT: lower prices or more scarce Dollars aren't the expected answer.
What’s wrong with setting the funds rate to be in line with other market rates? By definition market rates aren’t cheap or expensive.
