About as much as your comment based on the 10 seconds you watched of that video. 
@BassWrangler Ok,Master of all things Mechanical,WHICH system for blowing up flat tires on a vehicle that has been sitting for years and is sunken into the soil,the method I suggested,or the one your hero used?
BTW,if you REALLY think that VW had been sitting there for decades and only ONE tire was flat and that it held air when it was pumped up, I know of some ocean-front property in Arizona you may be interested in buying.
Not to mention that he puts that wuss winch on it and pulls it out of that hole and onto his trailer with the wheels rolling. After 10 years or so,the brake shoes on a "yard queen" are usually rusted solid to the drums and it takes a hub puller and a LOT of beating on the drum with a BFH to pull the hubs so you can get it rolling.
Yeah,some brake systems have "floating" brake shoes and you can cut or grind the head off the retainer pin that is on the backing plate,but some others don't.
Sometimes you can get lucky and the brake shoes will pop off the drums after a few smacks with a BFH,but other times you really have to work for it.
Sometimes the quick way out is to use water to soak the ground around it so the stuck wheels slide instead of try to roll,and use a little motor oil or something on the ramps and the floor of the trailer to help the whinch pull it up.

It is always easier to break stuck drums loose at home where you have all your tools,and can do it at your leisure.
The last one I faced one like that was a 55 DeSoto I bought from a guy in Georgia. He had stored in it an old hog pen,and it had sank all the way down to the point it was sitting flat on the ground. I had to jack it up one wheel at a time to pull the wheels off and take them to a local used tire store and have used tires put on them because they were too rotten to hold air.
BTW,since I am too old and stiff to do that stuff anymore,so I am just putting a steel hydraulic lift tailgate on my 06 GMC 2500 Turbo Diesel 4x4. This way I can just back up to one with flat tires or tries sunken into the ground,lower the tailgate,back up until it is under the bumper,and then use the tailgate to lift both wheels off the ground at the same time.
I also have a pretty serious battery-powered impact wrench.
Once I got round wheels and tires on it,I put short sections of 2x10's that I use as ramp extensions on my trailer under the tires before pulling,and used my F-350 diesel and a big chain to just pull it out of the hole. Once I got it on level ground it was easy to pull up on my trailer with the winch I use and the addition of a little oil to "grease the skids" while making the angle of the pull less steep.
I suspect a lot of the stuff I mentioned was done before the cameras started rolling so it would all fit into the time block they had available for broadcast. They may have even left a flat tire on the rear that they knew would hold air when they pumped it up as an "example of what you have to do to pull one on a trailer".
