I agree.
Unfortunately it is the economic viability that is faltering. "High-tech" is moving offshore faster than its being developed, and there is no value-added in a service dominated marketplace.
And in case you haven't noticed, the modern, efficient mass-transportation systems that I advocate are "high-tech" high-speed rail and maglev. The alternative fuel sources that I advocate for these systems is also "high-tech": nuclear and clean-coal technologies. And to address the growing demand for fresh water, I've also recently begun advocating construction of nuclear desalination plants.
None of this can be described as putting "everyone on the dole".
