For example, compare how the UK and the US handle compensation for lost future earnings in wrongful death cases. In the UK, judges are guided by the "Ogden tables", actuarial tables published by the British government. The judge will use the deceased's age to look up a multiplier in the tables, which will be multiplied by their income at the time of death, to derive a net present value of future earnings. While the tables are technically only a guideline, and judges have the discretion to deviate from them, plaintiffs rarely succeed in practice with convincing judges to do so.
By contrast, in the US, there are no such formal guidelines – it is largely determined by expert witness testimony before a jury. Expert witnesses have a lot of scope to argue for higher estimates, and often succeed in convincing a jury with those arguments. The result is unsurprising – compensation for lost future earnings is more generous in the US than in the UK.

Are you trying to say that one system is bad and another is good? They are different for different reasons, which can be explained by the structure of the society and what we expect courts to provide for us as opposed to other areas of government or private parties.
The argument though is, a lot of the difference is nothing to do with the factors you cite such as social safety nets, it is about the use of juries in civil cases, especially to decide damages. David Bernstein (professor of law at George Mason University) puts the argument better than I can in a 1996 journal article – https://www.cato.org/sites/cato.org/files/serials/files/regu... – see in particular the discussion of juries on PDF pages 3 onwards, and his recommendation on PDF page 6 that state legislatures should remove the power to decide damages from juries and transfer it to judges only
