Public transportation is non existent in a lot of the US and the cost of taking a cab is higher than a car payment. We have sprawling cities where if you don’t want to work a commute that would be 3+ hours each way you are precluded from most jobs and you better have 3-6 months of money saved to job search in your area at that point.
Millions of people are stuck in places where if you don’t have a car you’re going not going to finding much work or working a living wage.
The one in Panama actually makes sense because it is near the rainforest and acting as a buffer against them. These facilities only work if they are near the flies, you can’t use sterilized flies unless there is a population of flies to use them on.
When you put that together this almost looks like they are signaling plans to abandon support for the Panama facility and allow them to spread through all of South America up into Mexico.
