It's not a quote but the implication of Locke's entire discussion of property in his second treatise. He explains that value (wealth) is created by the labor expended to create products. It follows then that wealth is not fixed.
>He explains that value (wealth) is created by the labor expended to create products. //
This is not at all the same as:
>"You get money by bringing about the manifestation of value into the world." //
IMO value is created by labour enacted to process [raw] materials. You can get money however without creating value. Indeed a lot of trading appears to be a way to extract money without adding value. Optimisations to avoid wasted production are not creating value IMO. They can be beneficial, I feel, but I also find that we've gone way past the point at which financial markets are genuinely optimising the creation of value. The main mode of getting money appears to be exploitation of those expending labour to process materials.
Some poor unfortunate sell their kids to coffee plantations in Western Africa and a wealthy trader sits at a computer and extracts the value of the kids processing.
