The solution is more public housing (provided by the State or privately built and rented by the State). More money chasing the same number of houses will result in higher rents but the same number of homeless people.Sorry, just seeing this now.
This is somewhat simplistic with respect. The homeless crisis will not be resolved without understanding what has made them homeless in the first place. Homelessness is an age-old problem, with a variety of reasons of why people become homeless in the first place. The current crisis is worse insofar that a relatively new demographic has emerged in the statistics, that is families, sometimes working families are now adding to list. People who, in most other times, through their earned incomes would afford a mortgage or pay rent.
Using your own source, the 102,711 mortgages in arrears is a frightening statistic. The 2,335 repossessed homes is also shocking. So in the middle of a housing crisis, repossessions are at all time high!
I cant see any evidence that any freeze on wages would result in the homeless crisis being resolved. In fact, this crisis has emerged after a period of pay cuts and freezes.
In simple terms; take 10 people, eight of whom have €10 and 2 of whom have €5, who all want 8 apples the 8 people with €10 will get the apples. If every one of them get an extra €10 then the same people will get the apples, they will just end up paying more for them. It's basic supply and demand.
