I think the conflict is between those who value people more or businesses more. In the US, businesses are often seen as a core and fundamental part of a society. In many other countries, it is not. That's why you get responses like "Businesses exist to serve people, not the other way round".

There really are not many jobs where things change fast enough in one year that your ability to do the job is adversely affected. Including SW. I've looked, and it's hard to find a SW job that involves cutting edge technology (AI may be the exception these days).
I get the sense a number of people feel that the person who worked instead of taking the time off should be given extra credit for that work, but I do not find the argument compelling. At least where I work, he does get something extra for it - a higher pay. People who go on parental leave in my company do not get the same income while they are off as they did at work - they get a percentage of their salary (I think it is tax free so it's "about the same" as their salary). But everything extra (i.e. bonuses) is prorated - they get nothing for the time they are off.
