Wealthier ppl have new cars with stricter emissions. In fact, gasoline cars since port injection have made negligible amounts of particulate emissions (which is the only pollution that matters in this case, CO2 are only globally important). Direct injection might screw everything up soon (their intake valves foul like crazy). The emitters, therefore, are ppl with old cars; tractor trailers; city buses [0]; working class ppl driving, old ill maintained vans and pick ups. Really, the only significant particulate emissions I can think of from rich suburbanites are their gas mowers and blowers. But they're (a) polluting the air around their homes (b) quickly switching to electric. Now, if you want the rich sub-urbanites to pay to relocate the school, that's cool. I'm down. But they're really not the problem. [0] In my mid western city, at least, the buses are diesel powered and not LNG, and they appear to have the particulate filters ripped off. Dunno about Clark County's buses in particular.
