Just want to jump in here and mention that it doesn't even have to be a PTA, it could be any community organization focused on local student welfare and community building. The extracurricular programs at my school were/are heavily supported by the community and focus on student welfare.

I live in (what has turned into) one of the wealthiest neighborhoods in my city. The elementary school has long been the envy of many. Not long ago I asked a long-time teacher from a nearby city, with whom I serve on a nonprofit board, what it was about that school that made young teachers want to work there — was it the additional funds from parents? Her response was no: it wasn't the extra funding, it was the parents themselves — educated, cooperative, involved.
You say that like two of the three aren't privileges afforded more consistently to the wealthy. In either case, the operative function is the wealth-hoarding behavior of the parents.

Agreed; this is well-nigh indisputable.

This paints with too-broad a brush (and is needlessly confrontational). At what income level does earning money — in accordance with the rules that have evolved in society — become "wealth-hoarding behavior"?
