It's because TVs aren't subsidized by the government. The reason Doritos are so expensive is because, up until recently, people on welfare could get them with SNAP, so PepsiCo could charge whatever they wanted and had no reason to care whether or not you could afford it because their primary clientele were people who were using your tax dollars to buy them. You pay more because someone else is getting it for "free", and by "free", I mean you're paying for it with your taxes. Since the government doesn't buy TVs for people (with your money), TV manufacturers have to price competitively, hence the low TV prices.

Powering the next giant leap. A novel electromagnetic thruster that runs on lithium metal vapor was successfully fired up for the first time during initial tests at JPL. Fully developed and paired with a nuclear power source, these thrusters could reduce launch mass and support payloads required for human Mars missions.
