任何经济理论，研究经济生活，解决经济问题就好，这样比来比去的意义在于什么？

说到底，马克思的哲学里面认为有一个不变的东西，否则他也不会去找，也不会以为自己找到了

In Marx's articles,he always emphasize "value in use" In neoclassical economics and other kinds of economics except Marx's,"value in exchange"is  firstly taken into account.as far as I am concerned,nobody can produce all the commodity he need to use.So only under exchange can they get the value in use,and I think the theory of labor 's value cannot tell us how to get information,but the "value in exchange"can tell us.Of course ,Marxist's theory is a kind of valuable theory,but it is only a kind of ways to think of the world ,nobody can criticize every theory through moral critique.And in the so-called western economics,value exists ,and after Marshall,the price equals value.And the relative price,I think it is also important in economic decision.

从资源配置的角度看，价格比价值要实用的多。马克思想提出一个理论来支持阶级斗争，因而其理论抽象色彩浓厚，西方经济学侧重资源配置，因而对价格格外推崇。

马克思古怪,为啥认为劳动都是一样的,平等观念?
假定所有都有个既定的假设价格,并给出比对,假设的意义在与比对,比对的意义不是真的求值,是强调任何可变所以可比,偶想;在商品容易讲,货币里的意义更重要
