I never knew there were so many here, they are wonderful.
Well ... in many other european countries Aristocracy lived in properties owned by king and was just to collect taxes, they had good live thought but they weren't so rich because they had their king. In Poland king was elected in democratic way by aristocracy and was dependent from aristocracy... it was kind of democracy for 10% of people. In comparison 100 years after the end of 1st Polish republic only 2% of people in UK had similar rights.
Going back to money ... aristocracy was rich because king was weak, and king was just executing aristocracy decisions. That is why in Poland you can find so many palaces as long as they Aristocrats weren't working on despotic ruler.
