Is it true that good people are blessed?

I have 6 siblings one brother. The eldest is rich one most are poor. My other sister said my eldest sister is blessed because she's good to my siblings. " I dont agree with her because the eldest sister is not even good sister to me. I would say her husband is blessed because he's the good person and because they are married his blessings are shared with her despite her being arrogant and mean sometimes its like without him there's no blessings" Thoughts?
