those credit card fees have been around forever so I'm assuming they've been factored into the cost of goods & services; this is nothing new so merchants that are now tacking on a surcharge to cover those expenses are motivated by other factors, either a new way to make a few extra bucks because people are broke and/or lazy & will still use their credit cards, or a way to slow the speed of raising prices themselves leaving it to the customer to decide if they want to save by paying cash.
He's asked that all the time & his response is always that debit cards have all the same security & fraud protections as credit cards. No idea if that's accurate but I have no reason to think he's misrepresenting that either. Regardless, I'll stick to credit cards for those things unless/until they start whacking me with surcharges.
He also often talks about having NO credit score. I had never heard of that until I started listening to him, but apparently if you have zero credit cards and no loans for some set period of time you become un-ratable, you essentially have no credit rating at all. So the question he's always answering there is how do you qualify for a mortgage with no credit history or rating. He then hawks a 'manual underwriting' mortgage process through a company called Churchill Mortgage. Maybe he owns part of it, maybe not, but it's an interesting thing.
