How do rich people take advantage of credit cards?

Many wealthy people use credit cards strategically to maximize rewards, cashback, and travel benefits. Instead of using debit cards or cash, they often put large purchases on credit cards to earn points or miles. They also tend to pay the full balance every month, which helps avoid interest while still building credit history. Some premium cards also offer perks like airport lounge access, insurance benefits, and exclusive rewards that can add extra value.
