A welfare system is needed... however, it needs to be focused at rehabilitating people back into the workforce.
From what I can see there are a few ways in which a person would need help:
* Lost job - for whatever reason... sooner or later, someone will be out of a job with no time to have another one lined up. In cases like this... unemployment needs to be provided with a cut-off date corresponding to a reasonable amount of time to find another job. If a job is not found by the cut-off date, then the person can apply for more aid, but has to show proof of their efforts to find a job.
* Financial difficulties too great to support current children - sometimes unplanned pregnancies happen... sometimes a financial crisis disrupts a stable family. In such cases assistance needs to be provided for a reasonable amount of time - daycare and help with getting another job. The legal guardian(s) are enrolled in a program to help them get a job. The aid continues (but is significantly reduced) for a certain amount of time after their initial hire, then discontinues as they show stability in their new job).
* Debilitating Drug Addiction - regardless of how it happens... some people become hooked on drugs and cannot break the habit themselves. In this case, this person would have to submit to a drug screening (to verify which drug(s) are in their system) and be enrolled into a drug rehabilitation program BEFORE financial aid can be provided for them. As they progress through this, they will also be trained on how to get a job. There will be time constraints on the rehab... and then additional aid after they leave rehab -- this aid has a cut-off date to encourage them to find another job.
I also think certain criminal records need to be expunged after a certain amount of time... so that once their after jail 'punishment' is complete, they can have access to better jobs and be a 'normal' citizen again. I feel (just my opinion) that ex-con's make up a noticeable portion of the drug addicts so often noticed.
The welfare system is a privilege, just like any other form of 'giving.' There can be conditions... and yes, the potential 'recipient' can choose to 'tough it out' if they do not want to submit to the conditions in order to get the aid. It is their choice... they cannot, nor should be, forced to accept aid.
However, as stated once before... whatever aid system is put in place needs to have the goal of rehabilitating people back into the workforce --- not just throw out free food and/or money. There has to be an incentive to join the workforce... because the country is dependent on its workers.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
