"America: It's like Britain, only with buttons"

Ringo Starr's quote is a funny way of comparing the United States of America to Britain. By saying "It's like Britain, only with buttons," he is implying that the two countries are comparable in numerous ways, but the United States has some distinct functions that set it apart. This could be translated as a reference to the US's more modern-day technology and infrastructure, which is frequently related to using buttons. It might also be translated as a referral to the US's more diverse population, which is typically related to the concept of a "melting pot" of cultures. Eventually, Ringo Starr's quote is a lighthearted way of mentioning the differences between the 2 nations, while still acknowledging their similarities.
