How do you interpret the verses where Jesus talks about giving your riches to poor people?

These are some verses where Jesus says that giving all your earthly riches, you will earn eternal life:
Matthew 19:16-30: When the rich man asks about the eternal life and Jesus replies with Moses' commandments and the rich man says that he obeyed the commandments very carefully and Jesus told that to achive eternal life the man must sell everything and give to poor people and then follow Jesus.

Luke 12:13-21: The parable of the rich fool: But God said to him, "You fool! This very night your life will be demanded from you. Then who will get what you have prepared for yourself?"

Luke 19:7: Zacchaeus promises Jesus that he will give half of the riches to poor people and Jesus says that the Salvation entered Zacchaeus's house.

A few questions related to those verses:

**Why Jesus told the rich man he needs to give *all* he has, and Zacchaeus can earn the eternal life by giving only *half*?**

**What if someone wants to give all the riches to the poor people, but he has kids. Does Jesus want us to leave our sons and daughters without anything? The parable of the fool rich man says that God asked the man whom are your riches to after you die. Maybe he wanted to ensure a wealthy life for his descendents?**

**Does God really wants us to give all our earnings to poor people? For instance, someone with salary should give all the money he receives after a month of work to poor people?** I don't ask these questions to blame Jesus, I'm trying to understand what Jesus meant, because I'm 100% sure that He doesn't want us to starve to death and give everything to poor people.
