Supply chain issues are definitely still a thing... I'm in the trucking industry and without mucking in the weeds, it's not so much as material shortage (raw or finished product) as it's a buyer shortage. Meaning companies will only produce what they are going to sell. Having over stock is not profitable, as they are still trying to cling to the business model of on time freight. Not to mention the increased prices of fuel, taxes, and levies that are added into the cost on the back end which most people don't even see, makes it eve worse.
But a more basic example: There are shippers I used to go to couple or three times a week. Now I might go once a week cause they are not getting the orders to fill for multi shipments weekly. I also do a lot of raw material paper loads. (Huge paper rolls from various paper companies) They are even getting backed up cause companies don't want to spend the money to buy the paper when they can't use it right away and it takes up warehouse space, so in turn we as drivers are not hauling as much stuff in general.
Not all companies are out to price gouge, it's the big bastards that own most everything that do that. If we could get big business lobbyists and money of of DC, that would be a good start to make the Govt start to do what they are voted in for. Govern for the USA and not big business.
But yes, I understand that this can be blamed on a multitude of thing, political or otherwise, but at the end of the day when people don't want to buy product X, good on them, but then those that DO want product X are going to pay the higher price to get it, because of the higher cost to make it. It's a vicious cycle that most people refuse to accept and want to blame others for. But this started decades ago and it gets worse and worse each generation, but now add in all the "extra" things we have had in the last few years, and it made the whole pot boil over to what we have now...
There is no single "right answer fix" to any of this; never will be. All we can do is make our little bit of life easier for us and those around us. I try to make the world a better place than what I found it; always have and always will. That means more today than ever before.
