Even though we have already proven that money can make you happy (unless you are already quite privileged), we still have people parroting the old adage about how it can't?
This is the phrase that tells you who has never been financially unable to help a struggling relative or an ailing pet, who has never had to not eat for a couple days, who has never had to stick it out at a job where they were treated nigh-illegally in order to feed themselves, who has never slept in their car, who has used a public bathroom as their personal washing station, and who has never been bled dry and had life stopped in its tracks by supporting their spouse's cancer treatments for years.
If we want to argue social constructs, let's argue the negative of adhering to a norm of opinion after the alternative has been tainted with stereotypes, hype, and misinformation. No one wants to look "greedy" and "material" by saying they want money or that money would make them happy, even in a society where we already waste enormous amounts of food that is not spoiled and may trash our electronics after only a few years.
