Up until recently many 2nd generation came out of respect for their parents - now many come for themselves and are bringing their children. It seems that when there is more involvement, the relationship is more intense because of their history. They've suffered so much already that we just want to make it easier for them - we want to protect them, shield them from any unnecessary problems. The survivor family is smaller in size. There are fewer family members to help with varying situations.
Times are different - more people are working.
Jobs and even early retirement sometimes means relocating. Fortunately some of our parents are living longer. No one was prepared for survivors to live this long - especially due to the hardships they had endured. The health care system has changed drastically and there is definitely more required from family members in numerous ways. It is becoming harder to balance everyone's needs.
