Very few people hoard wealth. You imagine wealthy people like Scrooge McDuck with a room full of gold coins. It's almost always invested in stocks which helps companies grow or in bonds which helps finance public works.
Pretty sure a diverse portfolio will feature gold. It might not be in gold coins in the owners basement though.
Investing in stocks where most companies are doing their best to suppress worker compensation or out-right replace them with robots doesn't feel like it's doing much to help the average person either.
Public investment is on a downward trend since 2008 when governments had to save the bankers. What government spending there still is often has to filter through private service companies that are given government contracts. This usually results in good dividends and bad service.
