I'm against the disabling of a person by themself from alcoholism/drug abuse, and we the people end up paying the cost.
I believe I personally agree with the point you make, but I suspect there is no line you will ever find that shows you which people are "bludgers" and which are "legitimate". People involved in car accidents? Switch 'em off if it was their fault. People who marry smokers? No health care for them buddy. Brittle bones? That's your fault since you didn't eat right. Heat stroke? Let 'em melt...

Different countries do exercise different levels of compassion based on what the current policy is. But while I agree there is no system in any area of society that wouldn't benefit from a 'tune-up', so long as there is no consistent metric for "worthiness" of a human being, there will never be a perfect system of welfare.

I don't think that any long term investment in the stockmarket for 15+ years lost money.
Historically, if you take any 30-year time period, which would be a little less than half of your working life if you couldn't retire 'til you reached 67, you will have not only made money, but fistfulls of it.
First of all, people *do* lose money in the stock market, and the people who continue to claim otherwise make me worry for the state of your high school mathematics programs. You know, you can guarentee a win at the lottery if you buy a ticket for every combination...

If you were able to put money into almost *any* investment for 30 years you will have most likely make money, and it shouldn't be surprising considering 30 years is a huge fraction of a human life span. But that money comes from somewhere, it doesn't exist in a vaccuum. While a small number of people play the shell game, it remains exciting because there are wins to be made from other people's losses.
If your entire country starts investing in the stock market the
net gain will be substantially less because these things will happen:
(a) some people will get rich, some will be the same, and some will be worse off; or
(b) everybody gets safe stable investments, and ends up pretty much the same; or
(c) the stock market congeals, rich people get a bit less rich and the working class are better off, property prices sky-rocket and cancel out the difference
Imagine if all investment in the stock market was done through managed funds. Essentially you'd be turning the market into a flat landscape, which only grows over time because your whole economy is growing over time. Why not just pool your money and buy a tropical island somewhere? Or have each company start up a bank? I don't have to know the details of
any plan to know that using the words "stock market" or "personal investment" is just a gimmick. Either make euthenasia compulsory or raise the age and get over it.

And yes, there are probably a small fraction of "bludgers" that will fall out after the shake-out, but here in Australia there are several super-annuation funds that have already collapsed. Either you are all in it together or you aren't. I find your arguments disengenous to suggest that economic rationalisation makes you all better human beings. If you honestly believed that feel free to start a political party based on *everyone* not paying taxes, otherwise it sounds like you just want your kids to pay yours instead.

Countries are an advanced form of insurance. Governments even more so. The rule of insurance funds is that most people have to put in more than they take out. Anyone who says otherwise is either an anarchist or trying to rationalise insurance fraud...
