I'm not saying those things are complicated, just that you have no idea how they work so you are creating some elaborate fan-fiction to explain them.
1: Investment brokers
I earn money but can't be arsed to sit around analyzing stock and buying and selling every day, so I just pick a fund that's managed by a company who does only that all day every day.
2. Property tax: Levied by your town or city, used primarily to pay for schools, roads, emergency services, and other local infrastructure and services.
3. How they work: Your town or city makes a budget consisting of their expenses, less other income (state/county money, vehicle registration/excise, business licenses, etc.) divides that into the assessed value of all property in the municipality, sets the mil rate, then divvies up the expense among stakeholders.
You're welcome.
