Almost every philosophy has some good points. Marx saw the oppressed workers that others had "let fall by the wayside." Islam talks of giving alms and "Thou shalt not kill" and all that. Even the Nazis built some roads and ran a national healthcare system.
Liberal and conservative both have sound ideas (and some not-so-sound ones). The trick of representative government in a free society is to get more of the good and less of the bad. Somehow.
As for that "feeding the children", don't you mean, instead, to describe the point of view that children should be fed by the national "family" even if their real family can't afford it?
Thinking that "transcends nationalism" is not an easy thing to come by. Socialism ("Workers of the world unite!") was no match for forces like those that tore apart the USSR. Even religion can't compete (unless it means leaving nations in ruins, like the islamists of the Taliban or Boko Haram): just look at President Biden proclaiming himself a Catholic while turning up his nose at their pro-life dogma.
Oh, I quite agree, we should strive for a society where the ambulance comes for those who are sick or injured, the food is there for those who are down on their luck and the people screaming at their demons in the public square are taken to institutions for medical care rather than penal incarceration or, worse, simply allowed to keep screaming because it is one of their "civil rights" to do so. I'm sure you can think of many other such examples.
But somehow our society manages to combine the worst of "liberal" and "conservative" thinking on issues like these.
On the other hand there's the James Carville philosophy that the only thing in the middle of the road is yellow lines and dead armadillos.
There's something to that: thinking that there's some sort of ideal "third way" somehow splitting the difference between opposing ideas often runs into gridlock (or worse). Imagine Abraham Lincoln "compromising" with Jefferson Davis, or Lyndon Johnson "compromising" with Ho Chi Minh or Ronald Reagan "compromising" with Mikhail Gorbachev or Joe Biden "compromising" with Alexandria Ocasio-Cortez.
