These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anvilicious: While the satire in New York was a lot less specific and aimed more for a general dark look at what future society could become, L.A. goes way into specifics in terms of having an ultra-evil conservative president and some of the most obvious satirical jabs at L.A. culture.
Inferred Holocaust: Snake Plissken stops all electricity, all over the Earth. Actually, it does not seem like anyone could really consider there to be any "winners" in that movie, unless you think that cutting the power was going to stop the worldnote and by 'the world' we mean 'the United States' from tearing itself apart. Though, given that Snake's action effectively terminated the United States as a functioning political entity, it's likely that those guards would have more reason to shoot the president instead of his daughter for getting them into their situation than her. A healthy young woman would have more value in the After the End world to come than a crackpot ex-president.
Talisma reveals that she was persecuted and ultimately rejected from society for being a Muslim. Sadly, Truth in Television for many Muslims today.
The "tsunami surfing" scene's humor falls a bit flat in the wake of the 2004 Indian Ocean earthquake or the 2011 tsunami that hit Japan.
Snake shutting down the world is both this and hilarious on account of the recent Ice Storm in Ontario 2013. It's a double whammy since Canada was the original Escape Plan in New York, and this movie taking place in a fictional 2013.
Moral Event Horizon: The President has already proven himself a fundamentalist lunatic who purposely introduced a tyrannical new regime in the United States and views the rest of the world as scum to be destroyed. He later shows that he was serious about the orders he gave Snake when he orders his own daughter killed by electrocution even after her return to the mainland, visibly disgusting even Snake.
