(For comparison: the average public school student in the US costs $12,000 to educate. And yet plenty of people will say that even that is not enough.)
But the good news is if we don't fuck up, that number will continue to grow nonlinearly, just as it has for many decades. We will live to see it cross the point where it really is high enough to give everybody a comfortable life.
Why does it cost $30,000 to educate a class of 30 kids for a month? The salary of the teacher should be <$5,000. Double, or triple that to include rent and other costs. It still comes out at half of $30K.
Will it? When you look at most First World countries in general nobody there has to starve anymore.
In the Middle Ages only liege lords could get by without ever having to work. Nowadays, even middle-class people don't necessarily need to work till retirement age.
Use of food banks has increased in the UK, and hunger is very much present: https://en.wikipedia.org/wiki/Hunger_in_the_United_Kingdom
This is a policy choice. For many voters, it's far more important that nobody "gets something for nothing" than nobody starves to death. This has resulted in the benefits system being increasingly punitive leaving some people without money for food for weeks at a time.
