A new poll by the Kaiser Family Foundation shows concerns over rising healthcare costs have kept pace with other major economic worries. The survey by the Kaiser Family Foundation found that 44% of the more than 2,000 adults interviewed April 3 to 13 ranked paying for gas as a serious problem, compared with 29% for jobs and 28% for healthcare. The poll shows that healthcare remains in the forefront of Americans' concerns despite the mortgage crisis and growing overall economic woes, said experts.
