> Do you understand how incredibly privileged you have to be to afford a $500 shirt

Seems like a virtuously elitist argument against other elites.

Should we apologize for buying any luxury item?

If we only did the necessities of life, how do you think our world would look? What motivates you?

It is demeaning to others to feel apologetically bad about having luxuries that others don't. It is rude to judge others as privileged. The problem with the word is that it indirectly puts down the unprivileged. Everyone alive is privileged and lots of dead people are too. Be grateful for luxuries, sure. Denial and abstention can be just another form of being an arsehole.

Hipocrisy is hard to escape eh.
