What you fail to understand, however, is that there is a surplus of jobs in some undesirable sectors. DO something you don't want to. There will always be jobs for those to truly seek for it. If you break down the walls between 'this is a job suited for me' and 'there's no way in hell that i'd partake in this', then you'll find that the options expand exponentially.
Proof, where is your proof? It might as well be a useful lie unless you prove it. From my prior readings, many of the jobs in shortage, are, believe it or not, skilled jobs. These jobs by their very nature aren't readily open to everyone. You start with the basic, flawed and hateful assumption that Australian society is just full of bludgers who don't want to work. Whether you do this deliberately or you just haven't read very widely i am not sure. Time and time again though, the evidence proves all your assumptions wrong.
According to Professor Eva Cox from the University of Technology, Sydney:
At any one time, there are about 200,000 vacant jobs listed most of which are for skilled people with recent experience. Source
On the Truth-O-Meter, your claim that there are plenty of jobs out there and people just don't want to do "hard" or "icky" jobs is dead false. You don't even need evidence to see it, you can even work it out logically. Everyone can offer labor, it is not surprising that anyone can hire anyone to do labour (stack boxes, etc). It's much harder to filled skilled jobs because (duh) you require skills. This is why that the vast majority of openings require skills and prior experience.
Equally, you don't exactly know that when this comes into effect whether people will turn to crime or starve or whether they will suddenly find this new sense of 'forced inspiration' and change their life around.
You're taking a bet on this? You're willing to run society on such a cruel principal? Where is your heart, where is your compassion? This is not the sort of political ethos i want to see in Australia.
Force people to starve or turn to crime, in an effort to get the few bludgers who really do exist off centerlink to save you a cent of tax? In this effort turning many more to the street and crime? That is not at all pragmatic, kind or compassionate. It fails on all three.
But when we're talking about those who are essentially capable of doing so, but they refuse to take part and do something because it's deemed to 'physically difficult and draining', why should we continue to support these people?
This is a highly empirical claim with again, zero proof. Without proof, all this is a fantasy that is constructed in the mind to justify brutal policy decisions.
