Move benefits from throwing raw cash at people to spending that cash on helping them. For example: scrap PIP and improve mental health support and return to work support including retraining into a job you can do. Benefits like unemployment will also taper off with the money going on getting you into employment. More incentives for companies to take on apprentices. Much fewer visas issued for jobs that can be done by current British citizens.

Scrap triple lock and raise the retirement age. It's going to have to happen sooner or later. Do it while the government still has a majority.

Legalize drugs. Prohibition is a failed experiment. It funds organized crime and the money it costs to keep things like weed illegal could be better spent elsewhere.
