Yes, free markets should always be free, but when those free markets are used to launder illegal money, or hide money transfers associated with things like political campaigns, it should be investigated and prosecuted. I think when you have people running for President who know, and who everyone knows, have no chance of ever being considered a viable candidate, it's just to get campaign money that they can then use to "fund their campaign". Perhaps the house buying/selling scheme I mentioned is one way to mask the skimming of campaign funds. I think it is more likely organized crime doing it. It would be pretty easy to investigate, since the buyers and sellers are all documented in public records, although sometimes it is some LLC that is used to hide the name(s) of those involved. Celebrities will often do that so that people can't easily find out what homes they own.
