[Interstellar] In the end, did they get the entire population of Earth off-planet?

Or did they leave most of them behind to die of starvation?

Bonus question: if they had the budget to build self-sufficient habitats in orbit near Saturn, wouldn't it be much easier to do the same thing *on the surface of the Earth*?

We didn't get everyone off the Earth, nor did the Earth become completely uninhabitable. The blight destroyed our crops, one by one. But it didn't cross over to all of them. Some plant species are too genetically different for the the blight to make the cross species jump. Unfortunately, the blight resistant crops, such as certain vegetables and fruits, can't be stored like grains can, nor could we transport them across the earth like we used to. With the climate change and collapse of the bee populations of the 21st century, these remaining crops couldn't support a technological society. The humanity left on earth would regress to about 1500CE population and technology levels. This might not sound bad, but if you were one of the 9 billion staving to death, it would suck.

However, the Great Collapse was only a brief set back in humanity's history. Do you really think that a society that can create a tesseract and manipulate the interior of a black hole doesn't have the technology to genetically create blight resistant crops? All we need is the time to do it, and the orbiting habitats gave us the time.
