According to Business 2.0 magazine via CNN, even though suborbital tourism and space hotels do not currently exist, "[a]ll, however, have the potential to generate astronomical returns during the next decade."

The article also wisely mentions the existence of 3554 Amun, a metal-bearing asteroid that "contains (at today's prices) roughly $8 trillion worth of iron and nickel, $6 trillion of cobalt, and $6 trillion of platinumlike metals."

The rewards of space tourism and opening the space frontier will far greater outweigh the cost.
