The cost of getting to orbit, while still prohibitively high, is slowly getting lower every year. If NASA's X33/X44 program is successful and single-stage to orbit becomes a reality, the cost of launching stuff into space will dramatically decrease (or so NASA says) Anyway, I think that in 10-15 years the government will finally afford to send people back to the moon or Mars, and private companies will be able to profit from space tourism.
