It goes both ways. A corporation could choose to offer both options, and sell the benefits of the more durable product.
Walmart seems to have been pretty successful understanding that their customers want cheap, non-durable things. They are, in fact, the highest grossing company in the US by taking that approach.
Amazon, OTOH, has decided to let anyone sell anything, including durable metal gas cans, and is #2.
And Apple is #3 making premium items that people value highly.
So, sure, apparently all those models are viable. Just saying it's not a conspiracy that Walmart isn't selling metal gas cans in order to sell more plastic ones over time.
I never said it was a conspiracy, but when the policy is in place pretty much across the board of their spectrum of products, it is certainly a policy, and not an accident. That, sir, is not a conspiracy, but a factual observation, and yes, because of where I live, if I "need" something in a timely manner, it's often Walmart or another similar store that I go to.
Ok, if you want to modify your comment, that's fine. But "They don't want you to buy a forever one, they really want you to come back in a few years." is definitely conspiratorial.
