Appropriate work found and ring fenced from those with disabilities to enable them to engage in society and earn a living. The wages for this should be linked to a person ability to work, with even says 2-3hour a week providing a minimum income equivalent to current benefits. This would likely to be more costly than the current system but I believe it is worth while.
Not all disabled people can work even to a limited extent, and often the problem isn't the hours involved, but the physical and mental demands of most jobs. But yes, in the past there were sheltered workshops that provided these sorts of opportunities for many disabled people who could not have been employed in the open market. Most of these were cut under 'austerity'. It would be a good thing to have more such programmes again.
No ability to claim out of work benefits it should be funded through an insurance scheme to which you pay into from day one of working
What about those who were not employed from the beginning?
Make work scheme mandatory for those without paid employment (litter picking, street cleaning, factory work etc) to provide an income limited to the current level of benefits.
Apart from all other considerations, what do you think this will do to the wages of existing street cleaners, factory workers, etc.? If a job needs to be done, employ people to do it and pay them an appropriate wage. Don't treat it as a sort of 'community service' punishment for people who commit the 'crime' of being unemployed.
And many benefit claimants are not unemployed, but are already doing such jobs, and having low pay topped up.
People need to live within their means so if you can afford no children don't have them, can only afford one (us) have one etc
OK, but this is already happening to a large extent: families are far smaller now than in the past. And when people cannot afford to care properly for the number of children that they have, often they could afford them until an unexpected crisis occurred. In the last 15 years, there have been at least three unexpected crises of a sort that had not occurred for many years beforehand so could not have been readily predicted: the 2008 banking crisis, Covid, and the current cost-of-living crisis.
