There are three issues...
I almost never give to beggars, but I do regularly donate to the Simon. They have the expertise to allocate those moneys in the best way possible. Giving money to beggars is quite often simply going to the wrong people, and in the wrong way. So I don't have a problem with moving beggars from an area. They simply are interfering with the proper running of society. HOWEVER, I would be completely in favour of them lobbying the government, etc, for more money...but in all honesty, who on earth thinks that a FF/PD government would care less about people with no vote (I will be presumptious and presume the majority don't/can't vote). I would be in favour of them protesting in front of Gov Buildings...but that will never happen due to the nature of the people involved, and their problems. The solution is either a progressive, ACTUALLY CARING ABOUT THEIR CITIZENS government, or campaiging by a homeless representative group.
Secondly, people seem to imagine that the 4million could have been spent on building homeless shelters. Generally there are plenty of beds and the problem lies with the homeless's mental problems rather than the simplistic matter of a bed. A once-off lumpsum would be no use to this matter, and is better suited to a once-off item (such a building a sculpture, rejuvinating pride in their city for Dubliner's). The continous flow of money required for an item such as providing adequate mental care (or similar items), is best served by taking it from a continious source...such as a 0.1% raise in tax (or as Graham Hickey points out, simply leaving taxes where they are, and using that money for the less wealthy, rather than putting more pay in already-fat wallets).
Thirdly, I pay taxes. I deserve to get something in return for that. I have both paid more than enough for BOTH a Spire and to see my more-unfortunate fellow citizens have their problems seen to. That's what I pay taxes for...to get things done for MYSELF and for MY SOCIETY (which includes nice items directly for myself - like Spires...and which includes indirect items for myself - like helping less fortunate people)...not for governments funding racecourse clubhouses. It is the government's incompentance, rather than the fault of the Spire, that is to blame.
