Helped me a lot a few years back and got me from "you are fired without severance" to "you are paid for six more months, you don't have to come in and here is half a year's pay in severance". Companies want to shock you into submission, hand it to an external party, lean back end enjoy.
I don’t think you can name many things here that the American tech workers have to spend on, that are included in typical European social benefits package. For example, if you were thinking about healthcare, you would be very wrong, as American tech workers spend very small fraction of their pay on healthcare, smaller than a typical European tech worker.
Health care in the US is only expensive if you are poor and unemployed, sad to say.
Are you thinking of anything beyond healthcare? Youre correct that salaries and GDP are difficult to compare, but US disposable income pc is dramatically higher than almost anywhere in Europe, with the couple exceptions being tiny enclaves like Luxembourg or petrostates like Norway. Subtracting healthcare spending doesn't come close to closing the gap btwn the US and eg France.
And this isn't explicable by retirement either, as Actual Individual Consumption is also dramatically higher in the US.
Hell, I'm not even sure your hypothesis makes sense at first glance. If the salary difference was simply a matter of shifting govt spending into the personal ledger, wouldn't pretax incomes be as high in Europe? After all, much of the layoffs we're talking about are high-income enough that the employees would surely be net-payers in any mildly progressive tax system.
