Yes life support is very expensive and costs from $1,500.00 per day to as much as $5,000.00 per day.
So if you don't think someone is gonna come out of it and live or the doctor says that the person on life support can only live on the life support then it would be best to have the life support removed.
It can be a very hard decision to make to remove the life support but if the person has no chance of recovery then it's best for the person to just die and rest in peace.
Being on life support is not really living anyway so while it sounds bad to remove life support it actually is the best thing to do in most cases.
I would never want on life support myself after seeing other people on life support that never recovered.
However if you're a pregnant woman in Texas then if you get on life support the Texas law prohibits the removal of life support while a woman is pregnant.
