A conspiracy means that the truth about something is different from what we currently know. JFK, moon landing, flat Earth.

Where is the conspiracy with banks buying houses en masse? They intend to turn every middle class family into a permanent renter and take any profit of the housing market for themselves. This is exactly what’s happening.

We can simply say that this problem is more important than people believe, or that the media does not talk about it enough because it’s difficult to write about. But there’s no conspiracy here.
