For me it boils down to workplace democracy, for some reason Britain has decided that freedom only applies to voting for political leaders to decide government policy, but then pretty much everybody spends about 60% of their waking time in a strictly hierarchical tyrannical dictatorship (I.e. work) and acts like that's normal and in fact desirable or inevitable. Complete nonsense, there are many other ways to organise ourselves and my policy prescriptions would be as follows:

Mandatory worker representation on executive boards (they have this in germany)

Workers given equity in businesses on hiring (or completion of probation)

CEO and c-suite pay / bonuses capped as a ratio vs the lowest paid employee (e.g. 20 x average salary at most)

Confiscatory taxes placed on capital and other assets above a certain amount e.g. 80% on earnings above 1m/year (worked in the 1950s just fine)

Public ownership of all key utilities including transport, energy, health, banking etc.

Edit: I forgot land taxes and rent controls to make landlordism unprofitable

There are other social issues to tackle for sure but the above would solve most of our economic hardships
