It was easy to get tools around the working bits. You could go to a local parts store, pick up a water pump for like $40, and replace one in 30 minutes? That car was relatively complex compared to the cars my dad helped work on in the 50's, due to things like AC, additional wiring, and fancy 4-barrel carburetors. All of this to say that you take your simple video, and you walk someone really close to being able to do fairly major work on a car -- the knowledge is super immediate and practical.
Modern cars, you're facing the fractal nature of high tech. You have a problem with the engine mis-firing, you have a large number of potential issues. Is the O2 sensor causing problems? Injectors? Computer problem? Other smog reduction devices? What is the code and what does it mean, stupid cylinder 4 misfire? The car is smaller, so you might have to take off unrelated stuff to even start looking at issues. Coupled with the fact that modern cars tend to actually be more reliable, and the ROI for being a shade tree mechanic is much lower.
How many of those 30's kids knew 3 programming languages? My daughter is 10 and does. It seems like calculus wasn't introduced in high schools until the 1960s. How about the time to become adept at basic computer skills. You have so many more things to know, today. Each of the things has extreme depth. Your 30's car and 30's tractor had a lot in common, learn one and you know tons about the other. Now? Giant diesel tractor runs everything on hydraulic systems, with all wheel drive and GPS assisted steering. Knowing how your Chevy works helps little.
In those days, lots of things could be repaired. When I design a consumer product, it is fairly common to heat stake the enclosure shut -- you'll have to tear it apart to get at the bits. Since all the parts are so small and so efficiently designed (i.e. not over-designed), they're made to wear out and have nothing you can service. They're so cheap, you don't mind buying a new one.
