the houses in ireland where bought as investments where easy lending led to house prices shooting up artificially almost like a pyramid selling sceme where the only end is disaster
this proves nothing other than greed and false hopes is no way to run your life or the economy
you either have to provide social housing or increase wages drastically to allow people to buy
So you provide a reason why houses where artificially expensive, then present social housing as a solution.
Y'know rather than eliminating the reason that causes the high prices.
