[单选题]养老命题已经横亘在中国社会发展的路径之中,不容轻视。去哪里养老?让谁养老?与庞大的老年群体相比,养老服务业的发展并不乐观。据调查,目前我国的养老机构能为老人提供的养老服务寥寥无几。大部分的养老,还依然托付于忙碌着生计的子女,甚至依靠尚有劳动力的老伴、老友。虽然社会保障网渐织渐密,不少地方也出台诸多政策,借助民间力量,鼓励家庭养老,但这还远远不够。养老服务这个“朝阳产业”,何时能解“夕阳焦虑”?近年,随着我国老龄化社会的加剧,养老问题越发受到重视。在政策层面,国家出台了《国务院关于加快发展养老服务业的若干意见》等一系列文件来指导养老服务领域的发展。2015年11月初,国家全面放开二孩生育,社会对于“人口老龄化”“养老”等问题的讨论再次转热。政府作为国家权力的执行机关,更应重视“边富边老”这一社会问题,责无旁贷地以主导者身份,在充分尊重和发挥市场规律的前提下引导市场,努力构建良性的政社关系,确保社会、经济同步发展,满足日益扩大的养老需求。
