Yes - but imagine (God forbid) you have sick child that needs life saving surgery in the US. You're more likely to see your child live if you have lots of money. In some cases - money CAN buy you good health.
OK - it may not make you happy all the time but it certainly makes life a lot easier - without the constant worry of what lies ahead.
