Wit,

Yes, reproduction is a right and I don't think anybody on this board would ever seriously think that it could be challenged (although we've all certainly met people who have "sterilization" written all over them). The point was that people express shock and dismay that there is so much urban growth and traffic problems yet we continue to have more development and increased population. Don't you see a correlation? We aren't a farm-based society anymore so I'm not sure that 10 kids is a good idea because families don't need 10 free field workers anymore.
And yes, spending 90% of the money where 90% of the traffic is, is too simple of a solution. We can never keep up with the expansion either budget-wise or logistics-wise with all the hoops that need to be jumped through. There is much more to building more roads than just laying down some concrete. Telecommuting, mass transit etc. are a start... Simple solutions to concrete problems don't always work. Remember that we once thought that just putting in a bunch of hatcheries would solve all our "simple" salmon problems.
