EU referendum, brexit and the aftermath

"The benefits system is also too inflexible to deal with short term jobs."

Valid point, but that's the challenge: to make it easier for the unemployed to take on such work and then sign back on once it's finished. I'm not advocating that people with families, mortgages, etc. are press-ganged into such jobs, but there is a transient domestic working force for whom such work is suited - students for instance.

Universal basic income would solve this.
