I have noticed as well and this has been going on since the last world economic crisis that happened in 2007, I know it sounds like a cliche but things are not made in the same way they were made before, now all the stuff you can buy is some cheap junk that breaks at the first opportunity, while stuff that was made decades ago is still working because those products were made to last and even if you abuse the product you can always restore it and it works as if it was new, something really difficult to do with the technology that is being produced today.
Well.. this is strange. But you can't generalize everything. I am using my laptop from Dell for the last 6 years, and so far I haven't faced any issues. The same can be said about refrigerators, washing machines.etc. In fact the refrigerator which I am using is at least 10 years old. But if you are talking about mobile phones, TVs.etc, then I have to agree. The LED TVs don't last for more than 4-5 years. On the other hand, the old CRT televisions used to last 20-25 years without any major issue. But then you need to chose between quality and durability.
I have a Dell Alienware laptop, 17 R4 , if you know about laptops then you will know how decent this laptop is, I am not going to say great because obviously there are better ones, but this was amazing, especially considering I bought it nearly 4.5 years ago (January 2017). Ever since I bought it, it had its plug broken, so they brought me new cable, then keyboard started to get lose and broken and not even just one case, it was 3-4 and then they came in and said it was a production error, shouldn't be getting this many this quickly and that was like first year.
I also got the battery swollen like crazy, which damaged the case as well, the empty space under the numbers is now swollen because of it, I got my warranty over after third year ended so I had to open it myself and took the battery out myself. Now I can only work if I plug it somewhere because it doesn't have a battery. It has so many software errors that I had to do a reset to default 3 times so far, and I am not someone that downloads too many things neither, I work as a content writer so my pc barely has anything, maybe few games from steam.
Moreover, these days the CPU gets hot, sometimes as hot as 90c and that should close the PC, instead it continues thankfully and I have to reapply the thermal paste on it. This is a 4.5 year PC that I paid top market price at the time, think of all the bad ones and how terrible they could be.
