That's true, but most of my social group fits into this definition and the majority fly commercial 6 - 12+ times a year, all around the globe, either for vacation or business travel. They almost all own personal vehicles, replaced every 5 - 10 years, well before the end of life of the vehicle. I live in Colorado and it's common for this class to own/rent a second home or condo in the mountains and take multi-hour drives to those places on the weekend. Those lifestyle choices produce massive amounts of CO2 relative to individuals who otherwise live generally identical lives.

It doesn't take extravagances like private jets to contribute outsized emissions.
