Say I learn Chinese. Will this help in learning Japanese in the future? Will Japanese after Chinese be so minorly useful to the point that it'd be far better to learn Chinese very well than to try to learn both?

My reasoning is that as far as I can tell, and as far as many are saying, Chinese is going to be GREAT to know in a few years. Economically and for business this makes Chinese the clear choice. However, from what I can tell, China is no where near as clean or technological as Japan. It seems shady and run down, while it would seem really cool to be a part of the Japanese culture. Even so, I don't really like travelling very much and I do like money a lot, so I think this should be more of an economic decision than one for enjoyability.
