Imagine donating all your money to charity too, do you do that? The thing about comparing spending is that there is always more one can spend, and there is always more one can give away.
Sure. And there is always a better way to spend seventy-six thousand dollars. I suggested what I consider to be a better way. If you think carefully about it, you might even agree.
To be clear, I am claiming that it is objectively better to spend a vast amount of money on charity rather than on a suit. I am not "dictating" anything, I am stating an opinion.
I was also thinking this, but I think shaming people for spending money the way they want is counterproductive. Same as with veganism, claiming the moral high ground (even implicitly) can be very galling, even to people who would otherwise agree. I think it's cool if people want to spend their money to help others. If they want to spend it on a nice suit instead, it's not my cup of tea but there are much more harmful ways to spend it.
So $76,100 for a suit and a calculator. Imagine how many lives could be changed if that cash were used to, say, install toilets in rural India.
Elon Musk could, quite literally, feed the world with his net worth. But he chooses not to. I'm not sure what your point is. I don't what it's like to own a $75,000 suit, but I do know the tailor.
