In this age of socialist governments the pope should stay away completely from bashing trickle down in any way. It is the main vehicle through which the poor are helped which is what he claims he wants to do. He should be promoting trickle down enthusiastically.
The Pope's job is to promote Christ enthusiastically. I find it odd, with the original translation which implied an endorsement of redistribution, everybody was saying the Pope should not be promoting economic systems. Now with this translation, the Pope is being criticized for not endorsing free markets as enthusiastically as he should.
