I was thinking about that today. A city this big needs to diversify. But how can we diversify? Some ideas:
-Increase the size and funding of UNLV. Make the city attractive to the tech industry and possibly expand the "college town" around UNLV. Becoming a major research center could make us the next silicon valley. The uni is already set up on a plot of land large enough to contain much larger structures and research facilities. This is a bit self centered I guess because I myself am a UNLV student.
-Build more varying attractions. A giant roller coaster park on the scale of six flags near Ivanpah next to the new potential airport could attract new demographics so long as a rapid transit system is provided to and from the strip. The art scene in Vegas is also getting a lot larger and I think that the addition of a major museum and possibly an "artists colony" could mix things up a bit.
-Make the city an energy producer. Build a massive solar collection area near the dry lake beds around Boulder City. Clark County could get federal funding for this and all that new power could be sold to California. The efficiency of solar cells isn't there yet, but in maybe a decade this could be possible. Unfortunately Clark County isn't very good for wind power.
Using spoiler tags on this idea that some of you are morally against. Note that I am not kidding about this.
