How does the equity issue your peer described relate to the three pillars of sustainability

In my community, a big issue is how hard it's becoming to find affordable housing. Prices keep going up, and a lot of families can't find places that fit their budgets. Older homes are cheaper but often waste energy, which then leads to higher bills and more strain on the environment and newer efficient homes cost too much for many people to afford. I believe wealth and poverty make this problem worse because people with higher incomes can buy energy saving homes that lower costs over time, while others are stuck paying more for less. It creates an unfair cycle that's tough to break.
