I've seen exactly that image and others similar to it being used. On first impressions it seems fair that the taller person should be "discriminated" against. However life is very rarely this simple. For example :-
What if there aren't enough boxes to go round and they're a finite resourse? Who makes the boxes? Shouldn't this individual have some say in how they're distributed? Presumably they should be rewarded for their work to incentivise them to create more boxes for others to stand on. Could the shorter individuals not make their own boxes if they need them in oroder to watch the game? Is it critical they get to see the game?
To use this image to suggest it's fair some people should be given more than others so they can be "made equal" is incredibly disingenous! I actually saw it in the school where my children were being taught and ended up in a disagreement with the teacher over it's use. I find it worrying our children are being indoctrinated into this kind of "equity" mindset and that government sectors are promoting it.
The video i saw in school at the age of 13, sponsored by or made by amnesty international, depicts two men working by smashing rocks. One of them is huge, who smashes double the rocks and is therefore paid double.
Apparently they should be paid the same in that situation. That sort of rhetoric goes way beyond nonsense like standing on boxes. It is scaled up to mean we should get paid the same at all times. The eventual conclusion to that is full communism where everyone is paid nothing.
People do not understand that productivity is wealth, and reducing it reduces wealth of the country and the world, meaning there are less boxes to go around, because people dont get paid extra to produce more boxes per hour, thus, they wont do it.
People think i am just a sociopath, but in my world we would be collectively far wealthier and productivity would be so high to render all basic things so cheap they are almost free.
People whine about things being expensive, wages being low. That's because productivity is low.
Right now you have people in china working like mad to ship products to us, while we print money. You can see this in the USA most of all.
One day the Chinese will have a light bulb moment when they ban all exports. They will then open a twitter account and type GG.
Edit: If not clear, while some might be more concerned about race issues, it is all a single underlying ideology.
