Only 40 years? You're a newby! Yes, the landscape has certainly changed for the worse in the last 9 years with so many blends and brands discontinued, and STD has screwed pipe smoking to its benefit.
There are still a lot of blends available, and there are some very talented blenders out there. Have you tried anything from Watch City Cigars, Wilke, Peretti, Ken Byron Ventures, and others? They're not SG or GH&Co, then again neither are SG and GH&Co though they are doing their damnedest, but these other brands are putting out some very fine smokes in their own styles.
As for what things used to cost, big deal. Everything costs more. Why would a luxury item like tobacco be any different? When I was a kid, a movie was 25¢, candy was 6¢. A gallon of gas was 12¢. When I was a young man, rents were around $100 for a one bedroom, houses cost $30,000 in a good neighborhood where they're now well over $1,000,000. You could buy hamburger meat for around 50¢ a pound. McDonald's burgers were about 12¢.
Things haven't gotten more extensive, money has gotten cheap. So pick your splurges carefully and make the best of them. Go exploring. Things may be down, but there's still more than SG, GH&Co, STD, etal. And if, all things considered, you decide that it's time to stop smoking a pipe, then stop smoking a pipe. Unless you're an addict, it's no big deal, and there are other pleasures in life.
