I feel similarly mystified sometimes as I've never needed one. When my mom mentions paying off a CC bill, I think "why not just use debit?" Maybe she'll have to delay purchases or occasionally miss out on something, but it ends up being the same money.

There are also people who are below the income line of paycheck-to-paycheck, people with addictions, people who have jobs or lives with risk of injury and thus medical bills or unpaid leave for recovery, people who have a big family with needs they have to pay or travel for... and I feel people can use CCs because rich people culture pressures them to cling to things and the idea of being "successful" to attract peers and love interests... but that's just my subjective analysis.

Without a credit card, how do you buy anything online, or sign up for any SAAS? (the ones that don't accept Paypal, which is most). Using pre-paid Visa cards are possible sometimes (but not always accepted) but are also a hassle to manage as a primary payment method.

Booking travel online? All credit cards.

Renting a hotel or car can be next to impossible without a credit card to put down. Once I had to pay a $500 deposit to stay in a hotel for 1 night because I didn't have a credit card they could put on file.

We're talking about actual revolving credit credit cards, not debit cards. I understand that you need access to the Visa payment system to function in modern society, but you can trivially get access to that simply with a checking account.

It is absolutely not impossible to book a hotel room or rent a car without a credit card. This is a weird thing that HN seems to believe about consumer finance that has not all that much basis in reality. I book rooms exclusively on debit cards, and doubt there is really a hotel that will refuse to do that. You might not be able to book a car with Hertz, but who cares? Other major rental car companies take debit cards.

The Debit/Visa cards work for lots of things, but last I tried most places wouldn't accept them to have on file for damage deposits and such (hotels/cars). I have to admit, I haven't tried for about 5 years. A debit/visa is no different than a prepaid visa. On an actual credit card, they can push the charge through even if you don't have the money available (pushing you over your limit if needed). Visa/Debit and Prepaid Visa's can't go over the available balance.

I'm not sure about the sentiment on HN, but I'm speaking from personal experience. Any time I've tried to use a Debit/Visa when checking into a hotel they've required me to pay a deposit that was returned on checkout.

You’re not from the US. Debit means a whole different thing in the US. Unlike other countries, visa debit is functionally equivalent to a credit card, and the retailer doesn’t know the difference between visa debit run as credit vs visa credit.

Once I again, I have a credit card I use almost exclusively for renting cars, and I believe I invariably check into hotels using debit cards. I can't remember ever having a problem.
