Locke's Labour Theory of Value, the state of nature and European imperialism

1) Locke's Labor theory of value reflects a break with the mercantilist school, but not the phycioctats(sp?), it is very similar to what Adam Smith would write in 1776 and the labour theory of value that Ricardo would further develop (Marx is in many ways a Smithian and student of Ricardo)

2) Reading the text makes me ask the question, what are the implications of defining individuals as being a part of the state of nature?

3) How much of Lockian thought is tied to the imperial project (the state of nature exists in the Americas that Europe is civilizing)? Was such though implicitly or explicitly used to justify colonial domination?
