Who is going to help provide good health insurance for children of older parents who are seniors when the kids are 26?

Good question. The hopeful political end to this, and it is all political, is universal coverage. Until that point, hope these children by age 26 have a good job with health coverage. Society takes care of them for more severe problems if they have no coverage but this of course shifts the cost to everyone who planned ahead. Watch for this to be a big issue in the 2012 campaign.
Missing something ? Is there any adults in the house ???? One of the roles of the individual is to make something of themselves and not continue to be a dependent of their parents or the "taxpayer" to provide them with the basics. Get a job/start a business, do whatever it takes. Older parents need not worry abut this if they teach their kids to be self sufficient. If not, they deserve the burden.
