It seems like the stock markets (USA) growth is strongly correlated to inflation. The more money the government prints the more the stock market goes up. So the market doesn't actually represent value in a company but instead debt owed to somebody else.
What are the implications of this and is it a bad thing?
What would the market look like if we corrected for the money supply?
PS: I'm asking here because when asking at other places I was told to just not worry about it.
Nominal figures are not adjusted for inflation. "Real" numbers are adjusted for inflation (in economics-speak).
The stock market (e.g. S&P 500 index) has real earnings that have consistently grown over time (although earnings are quite volatile). The real dividends paid by the companies that make up the stock market have also grown over time.
Jeremy Siegel, a finance professor at Wharton, wrote a great book called Stocks for the Long Run that shows stocks have grown about 7% per year (inflation adjusted) over the last 200 years.

I think it's better to correct for inflation. The money supply can grow and it doesn't necessarily cause inflation (see the 2008 monetary response to the Great Financial Crisis as an example).

I'm not sure this is true. In the 70s, inflation was high and stock returns are low. In the 90s, inflation was low and returns were high. In 2021, inflation was high and returns were high.
