Why are timeshare companies being allowed to do business? a.k.a. conspiracy theory no. 6582

What are the disadvantages of banning timeshare companies, with legislation similar to the Multi-Level Marketing and Pyramid Selling (Prohibition) Act? Only the government can answer that, as all signs point to an industry that is breaking all the rules of corporate social responsibility. One possibility is that the actions of such companies keep the part of the population "occupied", such that they will not be thinking about more pertinent issues like human rights, separation of powers etc.
