I don't feel a bit of guilt, and if it weren't for purchases of all kinds, you wouldn't have all those jobs created and maintained.
There was a mini series in England called "The House of Elliot," and it's about two sisters who start up their own design house in, if I'm remembering correctly, the 1920s. Before they do this though, the older sister is working for a photographer, and he has a sister that's totally devoted to her charitable work. So much so that she'll give someone else her own food.
After the sisters start getting well known, the charity worker goes NUTS at a grand event for her own charity. She's ranting that if everyone had donated the money they spent on the dresses, jewels and whatnot, they'd be in clover. Kind of silly though because the sisters employ a lot of people she knows herself, and without that event, the caterers, servers, seamstresses and everyone else wouldn't have had a job to do.
Everything from low-end to high-end products have a lot of jobs connected to them, and when I buy a luxury item, quite a lot of people are getting a portion of that sale. Makes sense.
