What does the phrase, "Money talks, BS walks" mean? I replaced a bad word with "BS".

I've googled it, and I've found several conflicting meanings. For instance, [this Reddit thread](http://www.reddit.com/r/reddit.com/comments/c3dop/what_does_money_talks_bullshit_walks_mean/) has several interpretations. Ristin's response is basically the same as Urban Dictionary's, but his answer was downvoted:

> 
> It means that money can influence people and be used to get things done, but "bullshit" like sales pitches, marketing, deciet and so-on usually get seen through by most people. So, if you have money it 'talks' and can get stuff done. If you have to rely on BS-ing people, you'll be shown the door.

Another different definition appears on [wikipedia](http://en.wikipedia.org/wiki/Talk%3ABullshit#Money_talks).
