zahavasdad – I think you have a poor attitude toward these things. Whether or not something is a luxury is not up to you. If sushi is cheaper is that a problem too? Do you worry as much about non-kollel families who may have things you consider luxuries? I may not disagree on your point, but I most certainly disagree with your presentation and very much disagree with the idea that you feel confident that your personal opinion of luxury vs. necessity is valid.
I get the feeling (though it’s a guess) that you have things that you have worked for and you don’t like that someone else should have them for free. Perhaps some of what you have is considered superfluous in my eyes and I would find you shallow and materialistic if I visited. Would that even be an appropriate judgement for me to make or is it correct to say that different people and their circumstances will decide what is appropriate for tzedaka use and what isn’t.
