Not disputing long term damage to the talent pool in the US, just making an observation that it won't be solved until the issue affects certain groups.
You just reminded me of the dangerous crossroad in a town in my previous country.
It became dangerous because the regional council allowed a grocery store to be built there but the crossroad wasn't designed for heavy daily traffic. There were many accidents with small to moderate injuries.
As everybody knew it was dangerous, many people asked the mayor to do something.
His off the record answer was that unless a child or a few adults were killed, he wouldn't get the funding to build another crossroad.
I just checked on google maps and it's now a roundabout.
