[General Live Action Superheros] Why do so many Billionaire geniuses have such crappy security in their mansions? (Lex Luthor, Bruce Wayne, Charles Xavier, Oliver Queen, Tony Stark etc.)

They always seem to be getting attacked by things below what you think they should be attacked by: 

* Tony by being attacked by *helicopters* and getting almost killed and his entire mansion destroyed when he was investing all his time on *security*. (MCU)

* lex luthor so many times getting attacked in smallville, 

* oliver queen getting attacked on his home a few times (he did have a body guard and he seemed to be the most equipped in security compared to the others though) youd think he would just upgrade what he already has. danger he faces vs amount of security he has. on that has the best score given that at begging of the series he only faced assassins and normal people his line of defense was fine, now he doesn't have to worry much about the mansion...(Arrow)

* xavior getting attacked so many times and *losing* in x 2 he only had wolverine and colossus as security. sure he might rely on the x men and in x 2 his main line of defense was out on missions he has no back up at all when they aren't in the mansion... same thing in apocalypse.

* Bruce wayne in gotham seems to get kidnapped all the time and attacked alot. yes they dont step up their security

You'd think they would have top notch security but they never seem to have it. they often get attacked by the simplest things you'd think they have thought of how to counter but nope. Now if instead they would get attacked by things out of the ordinary or things they would have guess that would be fine but they get attacked by the simplest enemies.  anyone got a reason why? 

(granted i might be misremembering stuff... so correct me if i am)

He turned off his house defences when they almost killed Pepper just before the mansion attack didn't he? 

>lex luthor.  
   
I never watched Smallville.    
    
> oliver queen.     
    
What could he have done against the people who could invade his house?  
More guards? Security Surveillance? All of these heavily increase the chance that he's found as the Arrow.

It's a school, not a war ground.   
Would you blame your high school for not having defences against shadowy spec-ops forces infiltrating and assaulting them?       
And in Apocalypse, they literally teleport into the facility.  
You can't defend against that.

I don't watch Gotham.
