Malicious startup idea: a company whose business model is driving rent-seeking real estate speculators into financial ruin. The company would buy residential real estate in a low cost of living area, followed by setting up offices there and paying its employees a high salary to do absolutely nothing. When rent-seekers inevitably drive up housing prices to as high as wages will tolerate, the company sells its real estate holdings in that location and moves somewhere else.
