or, possibly, why lefties shoot themselves in the foot when they call for higher taxes on the rich

What do the rich really want?
certainly not more money.
they already have enough of that.
so they dont want more money to spend it, they accumulate more money to "keep score"
The rich want honor and respect. they want to be able to walk into a room full of strangers and be recognised as someone who matters.
The lefts solution is just that we should tax the rich more.
But this does not grasp the real motivation of the rich
the rich pursue money because money in capitalism is the source of "honour"
if you try to tax the rich, they will just take their money and move.
The better strategy is to "seduce' the rich.
Honour them for their benevolence.
Honour is a powerful motivator,
soldiers will die for a victoria cross (honour)
scientists will slave away an entire life for a nobel prize (honour).
yet where is the honour offered to the rich (who are largely hated upon)
there is NO system to reward the rich for doing what we want them to do....
treat their workers well and produce safe useful and environmentally friendly products .
Society should do a deal with capitalists. it should givbe them the honour (and love) they so desperately want .
you see capitalists are narcistists and ambitious.
Set up a scheme for them being honoured for looking after their workers and the planet and they will do it.
This isnt even a revolutionary idea.
Adam Smith, one of the founders of capitalism recognised that people have 2 main motivations, the love of money and the love of glory .
so rather then wait for the rich to grow halo's, how much more sensible to seduce them with the most powerful of desires....the desire to be loved.
What? No horse story? You're an imposter.
