Answer:
To help them pursue their dreams.
Step-by-step explanation:
When Milton's wife died, he didn't have anyone to share his fortune with, so he decided to donate his millions to the school he built for his employee's sons.
The kids that studied there, share one thing with Milton: the love for the chocolate and the interest in knowing how to make it.
The dream of Milton was to have a big candy company and he achieved it thanks to her dad, so he kind of wanted to do the same thing for the children and gives them the oportunity to build their own empires.
