Why did EVERY dual use Stadium FAIL?

Multipurpose stadiums used to dominate the MLB and NFL. Now there are none. Thank you MANSCAPED for sponsoring this video! 20% OFF Manscaped + Free Shipping code POINT20 at http://bit.ly/2RIgQmk In 1971, 20 of the 24 NFL stadiums had dual purpose venues. Oakland Alameda will be the last of these stadiums in use this year. Why did this happen? Why are there no more multipurpose stadiums? The answer is deeper than you think.
