It sounds like you are asking, do EAs ever apply folk-style interventions to elites, and elite-style interventions to “folks”?
In that case I think the answer is no:
The reason to help poor people, or sentient beings who are otherwise vulnerable, is that they’re relatively powerless and there are relatively easy ways to help them. People who are wealthy from a global perspective (which includes most poor people in developed countries) are more difficult to help.
“Elite interventions” as you describe them only make sense for people who have a lot of influence. It’s rare for someone with a lot of influence to be poor or vulnerable in the relevant sense.
