Indeed, a "stimulus" package spent on building infrastructure, etc, can, over the decades, pay for itself through the increase in economic activity as a result of the project. HOWEVER, with the Government, whether or not they target the right areas to develop is very much hit and miss - and the more developed an area is, the more likely the Government is likely to miss. A road in a developing country, for example, can connect two major towns, allowing for whole new levels of trade to occur. A new road in the developed world, on the other hand, will likely just serve to reduce congestion slightly for a couple of years. Governments may also completely invest in the wrong areas of infrastructure: say, working to provide the country with a 2mb broadband line, when selling the spectrum for 4G will allow for far more people to get a much more powerful connection, at much less the cost... without any spending from the Government at all (indeed, selling the spectrum will actually bring some money in for the Gov't)
Further still, stimulus doesn't just go towards building infrastructure. It goes towards bailing out General Motors, towards funding house purchases, towards buying new cars. These areas of stimulus are NEVER good for the broader economy, as these things are always best left to the markets.
And, finally, when the Government is providing these stimuli - which has a very low chance of being a well-invested infrastructure project - they always do it by borrowing the money. This is bad. I'm not going to go through the whole process, now, but it's because of the Government running deficits that inflation exists at all. Inflation was pretty much non-existant in the USA before the 20th century... because the Government never ran any deficits. It was only with the outbreaks of the World Wars, when the Government started running permenant deficits for the first time, and the moving off the gold standard (which allowed free printing of money, and, thus, even larger deficits) that inflation really started to kick off.

As for your last point... the UK isn't the only country running through austerity measures - at the moment, you're seeing Spain, Portugal, UK, Ireland, Greece going through it all. France and Germany will need to start in a big way in the next couple of years... Japan shortly after. I don't know if you're aware, but the Republican party proposed a budget with $6.2 trillion's worth of budget cuts over the coming years in the USA... so, austerity will probably be starting in the USA within the next two years, and definitely after the 2012 elections.
