@davidmcw This "economist" would have told you that "demand" for housing was not a factor Then c6 months ago he started saying "maybe we have imported too many people" Yip an "economist" denied demand and then suddenly re-discovered it Clown, utter clown ..

@davidmcw From the man that missed the warning signs of the last crash.. I'm good thanks.

Here’s what could get more expensive with Trump’s new tariffs.

@davidmcw It’s easy. Your neighbor keeps borrowing sugar and tools from you and never returns the favor. Got it?

@davidmcw These experts have never been right about anything that conflicts with their ideology

@davidmcw Dave is the old gaurd. Everything is shifting. move with it or be left behind. He, also said X would go bankrupt. Well, its the no1 app in the world now.

@davidmcw That’s why no one pays attention to trinity economic students .

@davidmcw Imagine an Irish Economist telling someone how to manage a country’s economy. Look in the mirror.

@davidmcw Another expert rolled by the BBC to entertain us.

Eyes to heaven. Tariffs are a stick being used to test the mettle of individual trading partners and to force readjustment of international systems of trade. The cowardly types still operating from old paradigms, sobbing and hiding behind Ursula’s skirt - will be crushed into the dust of history. Those who pick up the phone and negotiate directly will strike a good deal for their countries.
