Yes, the existing problems with foster care mean that it is time to find a new way to provide transitional housing for children with no other means, because the current system does not provide at-risk children with adequate support. Often times, children are taken out of bad situations only to find themselves abused in foster care.
There are far too many instances of foster children being abused physically and mentally, not fed a reasonable diet, not taken to the doctor when sick, and left alone for long periods of time. Evidently being a foster parent can be lucrative, because it seems that many just do it for the money and have no feelings about the children they are supposed to be caring for. It would be a shame to have to resort to the old orphanages of the past, but the foster care system is broken and must be fixed. Perhaps someone can come up with a new and better way of caring for these children. There are many children currently at risk in the foster care system and they deserve better care than they are getting.
In light of the many abuses which currently occur with children placed in foster care, I believe that it is time to change the program. First and foremost, foster parents need to be held to a higher level of accountability. Periodic visits by state officials should be the norm, and measures should be taken to protect children against unscrupulous foster parents who are just in it for the financial rewards afforded to them by fostering.
I don't think the existing system should be completely scrapped. Despite the problems, there are still families and individuals who are committed to helping children by offering them transitional housing. That being said, it's a shame that there so many children in the foster system. We need to do a better job of providing caring, stable housing for them.
Problems with foster care are inherently human problems and are going to be very hard to avoid regardless of the method of placing children into homes. The system does not need to be overhauled, but changes and extra care might be needed to ensure the children are being looked after.
