By my knowledge of the current situation, the majority of the wealth in many countries is held by a few individuals with incredible amounts of wealth. Much of it is in the form of stock options and investments, but around 0.5 trillion dollars in wealth is held by [just the top 5 billionaires](https://www.businessinsider.com/richest-men-in-us-wealth-gdp-bezos-gates-buffett-2019-1) in the United States. Those billionaires obviously have day-to-day living expenses, but none of them have ever spent or are ever likely to spend their complete savings. As such, if we factor in the other billionaires in America, it is reasonable to estimate that approximately 1 trillion dollars in wealth is not actively circulating in the economy. It's either in a savings account or generating new wealth that will stay with the same individual who is extremely unlikely to spend it.

If some of the proposed economic policies, such as Warren's wealth tax, were to be passed, a significant percentage (lets just call it 0.5 trillion dollars overall, for the sake of argument) of that wealth would be re-introduced to the economy. Is there a risk that this introduction could or would cause massive inflation as it was injected back into circulation? Why or why not? What policies have been proposed that would counter potential inflation risks, assuming they are a risk?
