11 people died during the construction of the Golden Gate Bridge. We have onerous safety requirements and red tape which is why everything is so slow. Very few people die on construction sites now. Do we want 11 dead people or do we want things done extremely slow? I guess as a society we have answered that question.
We've probably answered wrongly. Even money aside, how many more people die in traffic accidents due to the extra miles driven because of delays in construction?
Some regs are worth it, certainly, but being overly cautious is in itself unsafe.
