If LED bulbs are supposed to last for 10 years, why do I still need to replace them every 9 months?

I'm in a nasty frame of mind right now, and this is what my 'tism brain decided to laser focus on for several hours. I'm mad that my light bulbs cost 10x more than they used to, and don't last any longer, and my power bill is higher than ever.
Yeah yeah, I know, it's probably just capitalism shitting it up on purpose for profit. And bulb science is probably solid, I guess. I'm just pissed off that I just barely managed to scrape through this pay period with $2.78 left in the bank before I default on my mortgage.
Anyway, any lightbulb science comrades got any info?
Your bulbs might be burning out because of overheating. These bulbs have their powersupply in the bulb screw, so there's no real place for the heat to go. I have a ceiling lamp that causes normal bulbs to reach temperatures as high as 100c, and so they burn out every couple of moths. This might be your issue.
Edit: fixed misspell
Look for bulbs with metal fins where the white plastic is in your image. They're there as a heat sink so the heat disperses into the air rather than building up inside.
Even more so it's in the design. The ones that overheat are being overdriven to their failure point. Better LED bulbs have more LEDs so they can be brighter with less power and more life.
LEDs should not get that hot. That’s literally a part of the technology
The LEDs don't particularly (unless it's a very powerful one), their power supply does though. LEDs run on DC voltage, so they need a converter from the AC line voltage to not die instantly
Ahhhhh ok
