From my understanding of the free market economy, when there is an oportunity to make money, someone will step in and do the work to make a profit. However, sometimes it's hard to tell if such an oportunity exists.
For example, before cable, TV was transmitted via airwaves. Someone came up with the idea of putting up a bunch of directional antennas and recieving many channels and rebroadcasting it over a wire to subscribers for a fee. Since there was a demand, the idea succeeded. However, the person who thought the idea up may have thought that perhaps it was a bad idea and no-one would subscribe. For business idea ventures where the demand is unknown, how does one decide if the apparent cash on the table is actually there or not?
