Other than the environment, I doubt it much matters whether some rich guy has a corvette or jets the world.
It matters when you're contributing to increasing demand for oil.
In many countries, the prices of commodities is strongly affected by oil prices. Higher oil prices can mean a poor family in a poor country skipping meals. Of course, it's not just oil. Higher demand for food will also spike food prices globally because many countries import their food from another country.
I know I've been saying it a lot but ironically as poor living in a poor country, I've actually reduced the number of meal I eat in a day from 3 meals to just 2 meals a day due to higher cost of groceries. At this point, I'm even reducing the calories I eat per meal and I'm already borderline underweight and well within underweight territory after an exercise session. I do need to exercise due to high risk of cardio vascular disease and diabetes in our genes. I used to be prediabetic but thank God, I seemed to have been healed miraculously without any medical intervention. The Holy Spirit pushed me to exercise.
The increased spending all over the world, did not actually equated to higher income for me. I tried but my slow mind is just not good enough for the highly competitive work place. No one's taking chances with me to earn more. I have an investment, but with so little invested, it's only making little. So my regular work income + investment income isn't really rising in proportion in rising cost of living. My electricity use is already minimal. I can't give up internet because I need it for work. So I've been cutting back on my food instead. I already stopped eating fruits few years ago, cut back on calories last year and this year, I reduced my meals from 3 to only 2 per day with absolutely no eating in between. Ironically, it seemed to improve my health despite being possibly malnutritional.
A stronger economy isn't always better for everyone. It usually results to higher cost of living for everyone because people can't control themselves spending more if their income gets better and unfortunately, not everyone can take advantage of the stronger economy. Not all of us can work or run a business competitively. I have brain damage for example that's why I think slow.
We've not begin to talk about pollution. Even if there is no real proof that human activity is driving climate change, carbon emissions still have a large contribution to local air quality. It causes smog and smog can cause sickness and worst affect will always be the poorest in society due poor access to quality healthcare, can't afford to use air conditioning, can't afford to move somewhere with cleaner air.
