People who earn 6 or 7 or even 9 or 10 figure salaries can have problems too.
Yes, these people have a level of privilege not afforded to many, and money means they usually have more choices available to solve their problems. However gatekeeping and shutting them down by saying they are not real problems by comparing to the worst off in society (the homeless, refugees from war zones, etc) is not productive.
Yes, their problems may not the deepest in the world. Neither are those of people who argue with their neighbours over their kids being able to get back their ball from over the fence - but these threads don't get shut down saying 'think about those who can't afford a football'?
As a society, we seem to have lost the ability to consider things on their individual merits.
In any case, if my diamond shoes are too tight - then the right advice should be advised to find a reputable high-end cobbler together with a reputable high-end jeweller to repair them.
For the sake of completeness, I hereby declare that I don't actually own any diamond shoes.
