How can inflation be good for us? High inflation is a killer!

Everyone hates inflation, I think. They make our money become smaller. When we used to be able to afford more things, now we could afford fewer things with the same amount of money. Anyone without income will find inflation is scary even. As they watch the amount of money in their bank account reducing, they also realize things are getting more expensive. They may even start to think if they should get some income to reduce the impact.
