It sounds strange to me, too. I grew up pretty poor in the US, and we always took at least one family vacation per year. Often, it was a camping trip or the like. Sometimes, it was a visit to a city or national park. My parents were very, very frugal. We almost never had new clothes. I guess it was just a matter of what they prioritized. Looking back on it all, I’d say they got just about everything right.
