It’s about quality of life .
It does trickle down considering that nurses are taking overseas trips to Europe every 2 months and 800$ purses can be bought for 5$ and the only thing which makes it noticeable is a small hologram which nobody will check .
Of course people only look at yachts and mansions because when everything becomes equal the stuff which separates the rich from the rest of us tends to shine brighter and get all the attention.
Of course if you want everybody to be a millionaire then trickle down failed , but in the past experiments which tried to make monetary wealth equal for everybody caused a situation where quality of life collapsed for everybody….and being all equally as miserable is not such a great result and the number in the bank account being all equal won’t provide any consolation
