It's a good observation, though many of those are also food for poor people. Wealthy food is often a refined version of what everyone else eats, usually requiring a lot of extra effort and time.

Lobster is a famous example (though I am skeptical of the story that prisoners revolted over being forced to eat it too much; I have been unable to find a reliable primary source). A beautiful example is from the film Ratatouille, where the eponymous dish is contrasted between his mother's peasant stew and the $50 a plate Thomas Keller version.

Also lobster is really only good because they absolutely drown it in butter
