If you don’t take credit facilities but pay for your expenses in cash, you are considered a risk. Credit scoring based on credit card purchases is akin to being required to be spied on every step of the way just so you can access what you practically can without the credit in the first place. I don’t have a problem with people who are fine with that kind of behavior. But there should be a way of fair assessment even if you pay in cash.
I wonder how tough or easy it was for Egypt to destroy the tunnels. Or how fast they started breathing again. How do the people create anti-flooding systems in there? Complex but very interesting topic.
