Law-abiding people live a miserable life every day, while robbers and thieves live a very moist life. Horses and mules ride at the expense of others, and fair and decent people starve. Those who build bridges and pave the way for good deeds will be blind, and the children of bad people who kill and set fires will be perfect.

I don't want to translate the last sentence if I understand it clearly. It shows the unfairness of society and the helplessness of kind people. For reference only, it is better to give points ~

PS: The "son" here refers to children and grandchildren.
