In this parable, the "country that hates the master" is Israel hating Jesus, as he accepts and loves those that Israel rejected.
Those listening to the parable objected when the master took the single mina from the wicked servant and gave it to the one who already had received 10 cities. The master wasn't simply "making the rich richer"; he was entrusting his resources to one who would invest them wisely and diligently.
This parable was given as a warning to those who would (and did) reject Jesus, eventually crucifying him. Similarly, it's a warning to unbelievers now: if you continue to reject him, what little you have will also be taken from you. Believers in Christ will inherit the wealth he provides for eternity!
