Sonic R is about the capabilities of human achievement.Compare the lyrics of Living in the City, "where everything is free" and Work It Out, where "nothing in this world comes for free". Clearly, we've got to put forth the effort to make life more liveable for everyone. Technology and innovation can help, but we've got to do our part and contribute to our world. We can't be Robotniks and have machines for everything, we've got to work ourselves like Sonic and company.
