Remarkable
Remarkably, it was probably easier to sell stuff to people in the 70s than it is now. Ok, so all the consumer has to do is press a few buttons and try not to forget their password. But as a would-be entrepreneur, the moment you go near the internet, you have a world of pain - the list of people you have to get permission from, report to and pay a cut to gets longer and longer and longer.
My next product will be only available to people who send postal orders to my home address, which won't be listed on the internet.
