Of course they should but not just because they fear the end is nigh they should do it in any case.
The 'boom' has been underway a lot longer than the last 5 years and its pretty narrow minded to look upon it as a bad thing.
So we have become far more materialistic, but it sounds quite bitter to suggest that you prefered the Irish (summarised) when we knew our place.
Now it is not bitter, don't be so reactionary. That's typical of Irish, because I don't live in Ireland I don't know anything about my homeland! I am proud of being Irish but it's not the only thing in my life. Why would I want to keep myself down too
It is the absolute truth though that the whole property speculation thing was a load of BS, everytime I went home they were droning on and on about it. A whole language had developed since I was away consisting of First Time Buyers, Property Ladders, Buy to Let, Stamp Duty... it seemed to dominate everything.
Why do you need the banks and the developers to warn people, they make money, it is the government's job to regulate and to warn people and in the end it is the individuals job to make a mature decision themselves. the banks didn't cause the problem alone, it was the older generation telling their adult kids you need to buy now because look our house has increased so much and it was peer pressure and conformity. There was no regulation and no thought put into any of the new construction, it was obvious to me from seven years ago that high density development was the way to go in Dublin (environmentally, energywise, convenience, quality of life) but everybody in the surrounding areas wanted to get rich rezoning agricultural land for farmland and sure we all want houses even though they are 50 miles out of the city and you need to spend 3 hours a day driving in and out on jampacked roads.

The property boom thing wasn't anything to be so boastful about, it just resulted in a lot of overdevelopment in outlying counties in the main without any infrastructure that could even compare to a city in Asia. The valuation of everything was going up to massive levels but nobody could actually explain why!
The other thing that was obvious was the massive flash consumer culture that came in big time. When I left there weren't many SUVS, LV handbags floating round but they had really become ubiquitous over the matter of a few years. It just looked like a clone of any large city in the UK. Believe it really was a big change from when I left around 2000.
I lived outside Ireland for a long time so it was very easy to pick up on the changes. Overall it will be good for me when I go back because I can rent a good place for cheap. I think the last 5 years of the boom was good for getting a more diverse country but it didn't really add value to Ireland as a nation. I was setting up a business outside the country but I didn't even bother approaching any of my Irish friend to see if they were interested. They could easily have invested their spare cash but sure everybody knows property is the guaranteed way to riches... as if bricks and mortar were something that produced value. The property market had sucked up all the investment capital in Ireland that could have produced something that added value to the economy and to the future.
Notice I mentioned the last 5 years, not the lead up to it.....
