Thank you electron 1100...you are so right!
Here in Oz we've already had two murders over someone hosing their lawn. One in Queensland and the other in NSW. In both cases the people hosing were quite within their legal right to do so. Yet, the nutjobs that were playing water-warriors thought they had the moral high-ground - so they resorted to murderous violence.
This issue about wastefulness and the environment is primarily about money and very little else. It is en masse social and economic manipulation playing on middle class fears, insecurities, nihilism and morality. A good number of posts in here clearly demonstrate how easily people are manipulated into believing that their stance is morally and intellectually superior.
Lets take the 'America the wantonly wasteful' argument - so loved by many Europeans and some Australians. Of course anyone who has lived in the US for any length of time knows that most Americans live modest lives. They live in modest homes, drive modest cars and get by on modest incomes. They may, depending on where in the US they live, pay a little less for some consumer goods, energy, housing, income tax and so on, than their European and Australian counterparts. Though, they also, in most cases, don't get the same social services that post-war Europeans and 'some' Australians now take as a god-given right. Most of the Americans I know are very modest people in every respect. There is nothing intentioanlly irresponsible or wantonly wasteful about anything they do. The kinds of wasteful life-styles Europeans accuse Americans of living, most Americans can't even afford and the same goes for Australia as well.
BTW, often there are very valid and compelling reasons why people in the US and 'some' Australians, drive big petrol-guzzling cars for example, or why they don't do things like they do in Europe, or more efficiently or whatever - but I won't go into those now, can't be stuffed.
This is my slant - Using a front as opposed to a top loader makes absolutely no difference regarding the water situation in the developing world. It is also not going to make a real difference in drought affected areas in Australia. Here are our (Australian) governments allocating vast sums to save a few drops, nitpicking over crap, whilst they allow most of this resource to simply gush away. Then they place the onus on low to middle income households with propaganda, incomplete information and half-arsed moralizing. Most people I know aren't really wasteful, quite the opposite actually. They just want to get by without being brow-bashed every five minutes about how inefficient, environmentally unsound and morally reprehensible their 21st centure life is.
Anyway, the moral of my story is that there is no moral high ground to be derived from using a front loader, but I get very clean and well-rinsed clothes from my top loader. I also do this using less electricity, because I use gas to heat my water and produce solar electricity, plus I have a rainwater tank (but I don't like using it on my laundry), I flush the downstairs toilet with it instead.
