It seems that when you put money into the hands of the public broadly, they consume goods and services.  When you put money into the hands of the top few %, they have much less need for additional goods and services, so instead they invest it, which drives yields down and (consequently) asset prices up.  The real question, then, seems to be how do we get money into the hands of tens of millions of grasshoppers and not just a few ants.
