Awareness is not gained with money. Awareness is gained with investment of effort. Pay and investment have older senses of work and outcome. They've come to also apply to money as a proxy for work and outcome, but the origin of the meaning is different.

It is interesting the degrees noted. In Hebrew there's the sense of investing your desire, which goes beyond effort to controlling what it is you want. People will naturally expend effort toward things they desire.

tl;dr: In English awareness is gained with effort (not money). It is a trade.
