Final answer:
People pursuing 'pies in the skies' are focused on an idealized vision of an afterlife or a better world beyond Earth, while people pursuing 'pies on the earth' are more focused on making a positive impact on the current world and improving the human condition on Earth.
Step-by-step explanation:
People pursuing 'pies in the skies' or heavenly utopias are often focused on an idealized vision of an afterlife or a better world beyond Earth. They may believe in the existence of heaven or an alternate reality where everything is perfect.
On the other hand, people pursuing 'pies on the earth' are more focused on making a positive impact on the current world and improving the human condition on Earth. They are interested in addressing real-world challenges and creating a better society in the here and now.
While both perspectives have their own merits, the key difference lies in the emphasis on the afterlife or a future ideal state versus the importance of taking care of the present and working towards tangible improvements.
