We might pay out the arse in the UK in terms of taxes and NI but we get a very sweet deal in return for it, namely that folks who didn't prepare for freak disasters are still kept reasonably safe.
Since you live in the U.K. I will let you in on a little secret... The U.S. has a LOT of safety nets - you just never hear about them.
You may have heard about Medicare - specifically the idea of "Medicare for All" but have you heard about Medicaid? It is Medicare... for low income people, families (i.e. - have kids), are disabled, etc. Also, you can roll into an emergency room and get looked at - which is a stupid and inefficient way of doing it, but you can still do it - even if you are in the country illegally.
We also have SNAP - the supplemental food program - that we spend $60 billion on every year. Again, for low income people. The average person got $125/month - families averaged $250/month. I heard this program got expanded this year, but I don't know the details.
If you want to talk this year, people earning less than $75k/year are getting two stimulus checks totaling $1800 - more if they have dependents. If they were unemployed, they got another $6000 from the federal government on top of their state unemployment. Some states even got an additional 4 weeks at $300. So, they could have gotten $9k on top of their unemployment benefits - which were also extended past the usual 26 weeks. (Some states are shorter, some are longer, but most have 26 weeks of benefits.) In fact, in my state, people were making $1k/week for sitting on their couch for 10 weeks. I talked to a number of managers who said their employees didn't want to come back to work because they were making more doing nothing.
Hey - you can even get a free smartphone and plan under the Lifeline Program by the FCC.
So, yeah... Plenty of lifelines on this side of the pond - especially this year.
