Do you believe this stuff?

Social scientists have concluded people that live in central cities and surrounding berbs are more productive than those who live in small areas. That relationship between size and productivity holds regardless of education level, IQ, and experience of workers. To which I say is "bunk". Then why are the cities loosing population over the past decades? There is a small trend where young professionals are moving back to cities, but the number is minuscule compared to those leaving. However, if gasoline prices continue to rise (PP hates oil companies) and will remain high regardless what PP does, the latter trend above may increase but will take decades. Supply and demand forces will drive which way gas prices go, but additional gas tax will be assessed to main gas prices at $5 bucks + a gal. for long term. PP Secty of Energy believes gas prices should be equal to Europe, so small electric cars, wind mills and solar panel, will make US energy independent. US is subsiding Brazil for crude oil, while the US sit on billions gals. of crude and tens of thousands unemployed in the oil country alone. To which I say is a "bunk".
