Who coined the phrase “trickle-down government” and what does it mean?

Solution 1:

Trickle-down

The standalone combination trickle-down is in the OED:

trickle-down adj. of or based on the theory that economic benefits to particular groups will inevitably be passed on to those less well off; also transferred as n., a filtering down (of money or ideas). orig. and chiefly U.S.

[1931 W. Rogers in Tulsa Daily World 12 July iv. 7/3 What about the old Boys here on the home grounds? Well maybe this thing will eventually reach him in some beneficial way. Lord knows what way it may trickle down to him some day.]

1944 Antioch Rev. Summer 192 In agriculture, as in business, they are devotees of the trickle-down philosophy.

1949 H. S. Truman in Sun (Baltimore) 6 Jan. 6/1 We have rejected the discredited theory that the fortunes of the nation should be in the hands of a privileged few. We have abandoned the ‘trickle-down’ concept of national prosperity.

Later quotations talk of a trickle-down tax program, trickle-down housing program, ‘trickle-down’ process, trickle-down economics and a trickle-down effect.

Trickle-down government

The earliest use I found of the specific phrase trickle-down government appears to be in the Official proceedings of the 1984 Democratic National Convention, possibly spoken by Dorothy Vredenburgh Bush:

(Applause) It is bad enough to have trickle down economics, but the real evil of this last four years is Republican trickle down government, and that is what we are going to change.

Another snippet that appears to be from a 1984 Empire state report:

... there some philosophical difference you have with the majority?

POOLER: We view the world differently. I think they engage in what I call "trickle-down regulation" to be analogized correctly to trickle-down government. They think if you help the companies, in so doing you'll be helping the ratepayers.

The 1990 George Bush: 1989 seems to contain the phrase 14 times in total, including:

He wants $150 billion in new taxes. He wants $220 billion in new spending. That is not change, that is trickle-down Government. We do not need any more of that. His numbers don't add up. Anyway, he says he's going to just sock it to the rich.

...

Now let's look a close look at what he offers. Chris mentioned it, $150 billion, this is for openers, $150 billion in new taxes; $220 billion in new spending. That is called trickle-down Government. It goes right from the top into your pocket. And we don't need that anymore.

...

And yet, Governor Clinton has already proposed $150 billion in new taxes and $220 billion in new spending. You talk about trickle down, that is trickle-down Government. Give the Government you wallet, man, and step back and let Washington solve the problem.

The phrase was used much more in 1992 by President Bush when accusing Clinton's policies, notably during the third presidential debate.

Solution 2:

I’m no politician, but it appears this is a play on the term trickle-down economics. This is the notion that by decreasing “economic barriers”, such as tax rates on the wealthy and corporate regulations, it will stimulate economic growth. The term is often pejorative. In U.S. politics, Democrats will often employ the term (invoking its negative connotations, e.g. let the rich get richer) to describe Republican policies, whereas Republicans might use “supply-side economics”.

Romney’s turn of phrase is an attempt to flip the tables. A trickle-down government, presumably, is one where government bureaucracy grows so that benefits might “trickle down” to the masses – something Romney and his fellow Republicans are highly doubtful of (just as Democrats doubt the merits of “trickle-down economics”).

The Stimulus which President Obama signed into law would probably be an example of what Romney calls “trickle-down government” in that there is a huge investment within government itself (i.e. public spending versus “encouraging private investment” via tax breaks, subsidies, etc.) in the hopes that citizens see an improvement in their economic situation. This may or may not be flawed reasoning on Romney’s part, but that appears to be the logic.
