前几天中学几个老同学聚会，今天我突然想起个事情，又去看了聚会照片确认了一下，那就是， 参加聚会的同学都没戴眼镜。我们都是北京市某重点中学的，学习在当时算比较用功的吧。 而我家孩子他们班，还是小学，感觉目前90%都已经近视了，一半以上戴眼镜，还有许多白天不 戴眼镜但晚上用OK镜的。 我觉得不是户外时间不够的问题了，因为每天练田径的体育生也都近视了。 原来我会套用自己的经验，学习凑合弄弄成绩就还行，认真学学成绩还能好点，最后怎么也能上 个大学。孩子为什么学习这么费劲呢？ 但他们老说现在和过去不一样的，现在学的难，都提前学，找家教，竞争特别激烈，我就搞不 懂，那能咋激烈？ 但是上周LOF套利连续跌停，只跑出去不到10%的人，我也没跑出去，让我有了点不同的感悟。 就是市场容量有限，众所周知的事情，就是竞争激烈。 好好学习，上好学校，找好工作，拿高薪，已经成为全社会众所周知的独木舟。家庭倾全力用尽 各种资源想让孩子抢占个位置，现在就是比过去难了。我上学时候不同学校可能最后收入差距还 没那么大，这几十年发展，差个10倍有了吧。 其实我觉得股市也会越来越难，我前两年就感觉。老一代勇敢的股民慢慢老去，新股民基民都会 比原来具 ...
