When you consider that there is a loooooooooooooong history of ostensibly neutral regulations that have had the effect of contributing to making wealth creation harder for minorities, I can understand the NAACP's skepticism here. In the short term, this regulation will adversely impact minorities simply because they are more likely to own such structures. If this were combined with a program to assist in earthquake remediation, it wouldn't have the same degree of adverse impact, but that would cost money.
Agreed. If you read the article, no one is actually claiming that earthquakes are racist. While I think the NAACP's complaints are misplaced in this particular case, if you're mindful of this history, it's understandable why they're skeptical of this type of thing.
