<h1 id="我们到底应该怎么去看待父母"><a href="#我们到底应该怎么去看待父母" class="headerlink" title="我们到底应该怎么去看待父母"></a>我们到底应该怎么去看待父母</h1><p>爷爷小时候教我三字经的时候就说要孝顺父母，但是现在是二十一世纪，一个物质社会，人与人之间的竞争逐渐牵涉到了家庭经济实力的竞争。从小学上课外兴趣班开始，教育投资就是家庭支出的一大笔花费。或者这样说同等学习能力的情况下，花钱越多请的老师越好的情况下，相应的学到的也会越多。这也就是为什么以前总是寒门出状元，而现在往往成绩好的孩子家庭条件也相应地很好。家庭条件好的家庭往往父母受教育程度也会更高，对教育有更好的方法，而且也有能力为孩子的兴趣爱好买单，而条件一般的家庭很多孩子的天赋只能被埋没。</p>
