Hard hats (and gloves and eye protection and safety rails and automatic power cut offs...etc...) all made into legal requirements because employers refused to enforce their use. Every one of those regulations was opposed.
Automobiles...every seat belt rule, every shatterproof glass requirement...every airbag...etc...all opposed by the pro-business crowd as unnecessary over-burdensome regulation.
And now we have a limo service owner too cheap to maintain his vehicles. One might argue that if a professional inspector said a vehicle was unsafe...it should have been impounded or "booted" until repairs were proven. Who wants to bet that exactly such rules have been proposed...but not enacted because some pro-business lobbying group fought it?
Now a business owner will get charged ...and sued...but those 20 people are dead forever.
Yes...I blame unthinking citizens for accepting the lies of the moguls (large and small) who want play with human life for profit. We need to stop pretending that consumer safety is some Communist plot.
