Let me save you the click: this Bloomberg staff writer (I assume) is asserting that retirees are hoarding all the money to get the economy moving because they are spending 8% less than they can comfortably afford. Um, no. If you think that 8% means anything when put against the massive wealth redistribution from the middle class to the upper class over the last 40 years you're either naive or colluding.
This argument is the bullshit designed by the wealthy to keep everyone lower than them on the economic ladder fighting among each other over the scraps leftover from the wealth grab so that they don't realize where the money actually went. Fuck you for pushing this false narrative and fuck you for trying to make retirees look bad. Most of those people are on inadequate fixed incomes until they die and they have no idea how long that will be so they need to stretch their savings out for an indefinite length of time.
Literally the only leg your argument has to stand on its that *some* of the retirees are obscenely wealthy and they fit into the group that's actually crippling middle class growth, but you've segmented poorly which makes your argument lose credibility to anyone that's even glanced at this issue.
