@onepict 40 million adults of working age in UK * £18,000 per year (elderly already get state pension):
£720 billion
Taper it, like how universal credit (welfare system in the UK) already works; as people start earning more, their UBI reduces.
Given current median wages, and expected wage growth, you could probably knock the UBI bill to ~150 billion.
Universal credit already exists; make it opt-out instead of opt-in. Auto-enroll everyone. The infrastructure for UBI already exists, in the UK.
@libreleah @onepict no need to taper when you have income tax (or that already does the tapering if you prefer). That takes any means testing out of it.
