Depends on what you mean by my world.
Food prices, and availability have changed. And not for the positive.
Computer availability. You cant just go pick up pretty much whatever you want from a Best Buy any more.
Construction has been devastated. Most prices are still 50% over a normal year. With huge fluctuations. Been told prices can vary +10% a day. Steel, wood, gyp, paint, tpo roofing, rigid insulation, have all disappeared from Atlanta, and maybe other parts of the nation, at various times over the last year or so. The only comparison was when we couldnt get concrete for three months because of Mercedes Benz construction. But theres not a major construction project to explain it this time.
Labor shortages have been killer too. I have one project that should probably have 15-20 frames at it a day, they are averaging 3. Contractor has told me some days it's only 1, which might as well be 0. Some of the more advanced trades arent as bad, maybe 50% participation, but well below what it should be, but low/no skill labor just doesnt exist.
Lead times on items have grown as well. Sometimes it is just transportation issues, but it's just as likely to be labor or material shortages on their end. Lights were typically 2 weeks if it wasnt off the shelf, but now even stuff "off the shelf" is 6 weeks in most cases. LEDs are getting hit by the chip shortages.
In a typical year the contractors buy out their projects as they go along, depending on the item they may do it a couple months in advance. Right now one of my projects about to go under construction is trying to go ahead and buy whatever they can, even if they dont need it for a year. And on that project they still havent officially signed a contract with the client, so they could get stiffed for millions of dollars and have no recourse. That's how extreme things are.
At least what I am seeing things are on a dangerous tipping point in the field of construction.
