So what? This is one reason I hate Twitter, you can post a small snippet that doesn't really explain anything and people see it and think you are saying something smart.
Is he saying the S&P 500 didn't really go up in value by 32x and it some how just borrowed from the US government? Is he saying that both of those numbers are really just showing what inflation was over those years? I'm willing to bet this guy doesn't actually know what he is even posting about, hence the lack of explanation.
Also, I think the fascination toward the US Governments Debt is kinda stupid. IMO the important thing to look at is debt to GDP. If the government debt was 1T, but the GDP was 10k, that would be a bad thing since the government couldn't get anywhere close to paying back it's debt. If the debt was 100B, but the GDP was 100T, who gives a fuck that there is debt, it could be paid off at any time.
Currently the debt to GDP for the US government is $126%. Most people in the US have a far higher rate of debt to income. If you make 100k a year and have a 500k house, you are worse off from a debt to income ratio than the US government.
