It seems to me that in relative terms those with the least seem to give the most and those with the most seem to give the least because they are more frightened of losing what they have.
It’s like the parable of the rich young ruler and the parable of the poor widow.
Mark 12:41-44 New International Versions
The Widow’s Offering
41 Jesus sat down opposite the place where the offerings were put and watched the crowd putting their money into the temple treasury. Many rich people threw in large amounts. 42 But a poor widow came and put in two very small copper coins, worth only a few cents.
43 Calling his disciples to him, Jesus said, “Truly I tell you, this poor widow has put more into the treasury than all the others. 44 They all gave out of their wealth; but she, out of her poverty, put in everything—all she had to live on.”
I cannot articulate this any better it speaks for itself, a poor widow who gave everything to the glory of God why can we not do likewise.
