Vet2be1973 I agree with you, I just think we have different ways of defining liberal, and there are in fact a couple of different ways that it is used.
'Liberal' as it is used in American politics refers to "having political or social views favoring reform and progress"
However it has a different meaning when talking about the free market. A 'purely liberal' state (which can never truly exist) is where there are no government controls I. E. No regulations, laws, police etc.
On the end of the scale, an 'authoritarian' state dictates everything people are allowed to do, with resticting regulations and laws. In an authoritarian state, complete power lies in the controlling state.
Most societies over the last hundred years have moved to somewhere in the middle I. E. A free market, but with police, transport, ports, schools, banks, laws, etc. Provided by the state.
So when you say that both republicans and democrats have made big moves to deregulate the American economy, I agree. In this way, they are both adhering to the liberal philosophy (liberal in the sense of the free market) that the market runs best when it is left to its own devices. The gfc is evidence that excessive deregulation, while providing large economic growth over the short term, will not lead to stable or equitable societies.
If 'green belts' were referring to money, we would assume that is American money. (A quick google search indicates that the pound comes in a variety of colours, and Muse are a British band.) Perhaps they are referring to how we blindly adhere to the us idea of exponential economic growth and deregulation?
