However, there are people who may be flying somewhere for a funeral. They may absolutely have to be back at work the next day or face termination.
It sucks but in the situations you describe maybe the person shouldn't be flying. Its easy to get mad at the airline when someone is involuntarily bumped but it could have been a storm, or an accident at the airport, or one of many other unlikely but possible issues. If the cost of a delayed flight will cause you to risk loosing your job, or miss a wedding, funeral, or some other event maybe you should plan a day of contingency into your travel plans.
Except for buying the most expensive tickets, there's no option to buy a ticket where you won't be "voluntold" to leave the seat you're already in.
What other option would you like? If you want a cheap ticket be aware of the fact you might get bumped. If getting bumped isn't OK then buy a more expensive ticket. Ya a first class ticket costs a lot more but in addition to complimentary alcohol you are less likely to get bumped. If getting bumped is a big deal then the cost of the ticket probably isn't.
The other really important thing to remember is that as good as the industry generally is at getting people to their destination at about the time they say they will there is always the possibility that there will be some issue that prevents you from getting where you want to be when you want to be there. It could be weather, or mechanical, or airport shooting or... If you absolutely have to be somewhere on Monday morning you shouldn't be flying on the last flight out Sunday...
This is a bug in the Linux kernel, affecting most operating systems that use this kernel.
Also, if security loopholes are discovered and exploits made, and your software didn't change - then it did "degrade" because now it's not as secure as it once was.
I wouldn't say that its not as secure. Its just as secure, its just less safe because the exploits are known.
Just opt out from the credit system
Without credit, how do you buy a roof to keep over your head? Cities tend to arrest people living in tents, and renting a house or apartment is borrowing.
You could buy a house with cold hard cash.
Never call a man a fool. Borrow from him.
