Not that I'm an economist, but there's more of an intuitive link between tax cuts -> profits -> stock market gains than there is between tax cuts -> ... -> underconsumption -> Great Depression. Edit: Although after reading a bit more about this, it seems like you're on to part of the Keynesian explanation in which tax cuts are only partially responsible but goes something like tax cuts -> profits -> stock market gains -> overinvestment -> overproduction & underconsumption -> Great Depression. Although there are definitely some factors I left out there that have to do with their explanation for why it was the Great Depression that time around and not just a more typical recession, which they attribute to the same cycle which is supposedly inherent in capitalism without government intervention.
