We must be to close to election season. Some people want higher taxes regardless.
To me the problem with your filibuster is:
1. Since some wines are overpriced, these other wines should be overpriced also;
2. You seem to be asking for higher prices for the "old vines" wines regardless of actual quality! I drink some "ov'ers" that are wonderful. I've drank others I wouldn't buy regardless of price.
A concept you may not like is that higher taxes/prices is not always the answer. But that's IMO.
