It is much easier to put existing resources to better use, than to develop resources where they do not exist. - George Soros

‘The EU needs to transform itself into an association that countries like Britain would want to join, in order to strengthen the political case,’ Mr Soros said he was convinced it was the ideal time for the EU to reform itself and prepare the ground for the UK staying inside the bloc.

Let's deal first with your general theory of reflexivity.
Essentially, it has to do with the role of the thinking participant, and the relationship between his thinking and the events in which he participates. I believe that a thinking participant is in a very difficult position, because he is trying to understand a situation in which he is one of the actors. Traditionally, we think of understanding as essentially a passive role, and participating is an active role. In truth, the two roles interfere with each other, which makes it impossible for the participant to base any decisions on pure or perfect knowledge.
Classical economic theory assumes that market participants act on the basis of perfect knowledge. That assumption is false. The participants' perceptions influence the market in which they participate, but the market action also influences the participants' perceptions. They cannot obtain perfect knowledge of the market because their thinking is always affecting the market and the market is affecting their thinking. This makes analysis of market behavior much harder than it would be if the assumption of perfect knowledge were valid.

Now look at the ideology of American supremacy. It has a solid foundation in reality; namely, the United States is the dominant power in the world. The current government believes the United States ought to use this dominant position to impose its will on the world. That is the misconception. This approach is not what made America great. America did not arrive at its dominant position by imposing its will on the world.
My position is that America is great precisely because it is an open society, and an open society recognizes that nobody is the ultimate arbiter — and that we may be wrong at times, even if we are powerful. We must be open to criticism and respect divergent and different views and interests.
