My grandfather dropped out of high school to work his entire adult life in a phosphorus mine while farming on the side to make ends meet. He never traveled more than 1,000 miles from the place he was born, and died before 60 due to lung disease.
I work in a climate controlled office. My wife and I are taking our kids on vacation next week, we thought it would be fun for them to ride on an airplane for the first time, and Disneyland seemed like a good place.
I feel like a lazy shit whenever I think about how my grandfather (or even my father, who was 6 when they got indoor plumbing in their home in the 1950s) worked to provide for their families.
The fact that your nephews are college graduates with 3 square meals a day counts for something towards "standard of living", I think.
