I understand that aspect, but I would need a withholding table to compare what I pay in insurance what would be deducted from the wife’s paycheck and mine.UK has no equivalent of a tax withholding table.
However as an idea in 2019 the NHS per person for the year in the UK cost roughly $4700, compared to a US per person cost of $11000.
US is roughly 40% more costly per person than the next most expensive, Switzerland. The UK is something like 13th to 15th, depending on the analysis.
We get bombarded with many unnecessary tests, and in some cases care can be Ponzi scheme by those that provide it.
