Yeah I keep repeating myself but it's important, if you're saying "how can stocks keep going up?" stop thinking that way and say "Can the dollar keep going down?"
The stock market has not rallied, the dollar got bitch slapped.
IMO to understand the market you need to change your denominator in value calculations to Gold instead of USD. With that view we've been through a ~80% correction or essentially flat depending on where you measure from. So essentially the Great Depression, just papered over with money printing. Changing how you look at value helps one to understand real vs nominal returns. I tend to replace Gold with Bitcoin as a denominator but that skews things cartoonishly just due to how Bitcoin has performed against everything else.
First chart is from a year ago, but you get the idea. Worth looking at charts in the entire thread for more context.
