I'm glad you pointed out the irony of the term "trickle down". That was a flag for me, too.
I think if there were a compendium of words and phrases that always means the opposite of the message they're used to convey this one would be top 5, maybe 10, somewhere behind war is peace and slavery is freedom style rhetoric.
I'm not a violent person... in fact I border on passive, but I still wish it was ok to punch someone in the mouth when they use it to spew bullshit all in my ears. You never really get it all out.
