The proposed SSI Restoration Act would:
• Raise benefits to the poverty line
• Update asset & income limits
• End marriage penalties
Using microsimulation, we estimate the result: SSI household poverty falls by nearly 60%.
• Raise benefits to the poverty line
• Update asset & income limits
• End marriage penalties

The fiscal burden of UBI is hugely overblown. And what of the fiscal burden of poverty? Is that costless? Is chronic mass insecurity costless? And the cost of UBI is its net cost, not gross cost. It can even be started small in a revenue neutral way. And it would stimulate GDP growth.

I have a microsimulation paper looking at the impacts of various SSI reforms that I am hoping to get out into the wild by the end of March and I now am worried there won't be a Social Security Administration capable of administering the program at all in a month.
This year marks the 90th anniversary of the passage of the Social Security Act. This is/was a monumental achievement that served as a foundation we have built on and should continue to build on. Musk, however, appears intent to burn it all down.
Between SSI and SSDI this is something like 13-15 million people are suddenly going to experience problems getting their questions answered and difficulties resolved. And there is a backlog of millions waiting for their disability status to be adjudicated.

That's a strange failing when estimating the cost is so easy: just multiply the number of affected workers by the average employer national insurance. Gives you £6-7bn.
