You're right, but focusing on Pelosi when Biden himself is an excellent example smacks of whataboutism.
It isn't a whataboutism (since she and Biden have very much been working together on behalf of the oligarchs), but it looks like one to the casual observer, which is probably why you're being bombarded with unfair downvotes in a Liberal (as opposed to Left) leaning community.
Oligarchy, like when Johann Rupert influences the South African markets and politics through his massive wealth and business empire... Or is it only oligarchy when Americans do it?
