My sister makes $270k a year as a doctor and has stated she needs a new credit card for traveling points and a lower interest rate. She makes about $13k a month and also is a partner at her practice. Can someone help me understand how a credit card can help her at all financially when she makes more than most of the world.
The world is based on credit now, simply, if you want to rent/buy/lease, something expensive you need good credit. Credit can be built from loans and credit cards.
