I used to think this but I think that's only true for the low-profile wealthy folks. And they voice their opinion indirectly, like through owning media companies.

The people that feel the need to be loud and in the public eye aren't necessarily playing 4d chess. It's really just an ego thing for them.

The wealthy who keep a low-profile are the smarter one's.

Yes, deciding to be famous AFTER becoming rich is a choice, and arguably not optimally intelligent.

Many in these positions get there by being really good/smart/lucky at something once and then having a war chest of capital to deploy for life.

It doesn't mean they are a polymath genius with unique worthwhile insights into all facets of the human experience. In fact, it may almost be the opposite. The hyper focus and hustle required to attain what they do often requires withdrawing from the wider world, not being particularly well read, and living in a socioeconomic/political/work bubble.
