Is constant generosity a trap? The psychology of 'take away what you give freely and create an enemy

I've been thinking about an old saying that roughly translates to "give someone a cup of rice as charity, take it away and earn a cup of hatred." I've noticed this pattern where people who receive ongoing help or gifts often start seeing it as an entitlement rather than generosity. Then when the giving stops or decreases, they feel betrayed or angry - even though they never "earned" it in the first place.

Does anyone else see this in personal relationships? Or even on a larger scale with social programs? It seems like there's something in human psychology where regular giving creates expectation rather than gratitude, and I'm wondering if there's a better approach that avoids this trap.
