There are many theories to power, be they liberal, socialist or otherwise. Many have been developed over centuries of thought, which pick apart the very nature of our society and world order. But of all the theories that I’ve come across, one sticks out more than any other, and it is the reason I hold such strong free-market/anti-state views. It’s called Public Choice theory, but don’t ask me why, because it seems to explain why any one but ’the public’ makes choices today.
Public Choice theory is modern, having only really taken off during the 1960’s, but I believe it grants a very realistic and worrying view of Britain’s power structure, and exposes many very deep scars which socialism and Keynesianism unintentionally inflicted on our country. It was heavily developed by the US economist James Buchanan, who won the 1986 Nobel Memorial Prize for his work, and who advised Margaret Thatcher through the Institute for Economic Affairs during the late 1970′s.
Just like capitalism, Public Choice theory is based on two simple assumptions about human nature. Firstly, that humans are principally self-interested. That’s not to say we’re selfish, which is somewhat more immoral, but rather that we will always aim to fulfil our wants and desires, economic or otherwise. Secondly, that humans are rational; when presented with a series of options, we will select whichever makes us the most happy for the least cost. Rational Choice theory, as it is called, has come under substantial intellectual attack in the past, and I don’t personally believe that all humans act completely rationally all the time, but as a model for human behaviour, I’d say it provides a pretty good analysis.
The answer is C.
As a science website says, "Scientists think they know why the Ancestral Puebloans disappeared. The primary culprit, studies suggest, was a megadrought that would have made it impossible to grow enough food to feed the tens of thousands of people living in the region."
If you didn't know, drought represents the lack of rain.
