I'm very dubious about the 'logic' behind austerity. We're hovering in and out of recession, at the moment and the solution to get out of recession, if I understand things correctly, is for people to spend more.
So what does the government do? It cuts spending. Austerity cuts mean companies that rely on cushy government contracts losing out. It means those self-employed dealing with a reduced income, and it means larger companies having to lay off staff or abandon plans at expansion. These people with less money, and others scared by the layoffs or by government pronouncements that we all have to chip in and do our bit in harsh times, will tend to spend less, thinking, rightly or wrongly, that they can't afford luxuries at times like these.
This, in turn, hits the income of those who provide said luxuries, exacerbating the problem further. It seems that austerity cuts are one surefire way of hurrying us into recession, not a way of saving the economy.
Paradoxically, some cuts could increase government spending elsewhere, as people who used to be indirectly supported by the government through their wages, are now entitled to various forms of government support through being out of work.
Of course, I don't really understand economics, but then I strongly suspect that nor do the politicians and talking-heads advocating these measures. It's an ideological response to the crisis from the right.
