材料一：为了落实结构性减税政策，我国政府将个人所得税起征点提高到3500元，这意味着，调整之后无需缴纳个税的人群将增加约1200万，工资薪金的纳税人一年可以减税1440亿元。另一方面，新的个人所得税征收条例，将原来月收入超过80000元至100000元的部分的征收比例，由40%上调到45%，这意味着少数高收入人群的个税将有所增加，对此部分高收入者表示不满。

（1）请运用所学税收知识，对部分不满意见者进行劝解。（4分）

材料二：改革开放以来，是我国城市理想的重构时代。人们提出了很多新的口号——文明城市、园林城市、生态城市等。有人提出了宜居城市的六大指标：

衡量宜居的六大指标

社会文明度	贫富差距小，社会保障覆盖率较高，文化包容性较强
经济富裕度	生活上没有很大的经济压力，相对富裕
环境优美度	生态、气候、人文和城市景观。对文化自然遗产保护应做得很好
资源承载力	人均资源总量，人均城市用地面积，食品供应安全等指标
生活方便度	在城市交通、商业服务、教育文化体育设施、绿色敞开空间、公共医疗卫生服务等方面
公共安全度	有完善的预防、应对自然和认为灾害的设施、机制和预案，政府对公共安全事件有较强的处理能力

包容是一个宜居城市的深刻内涵。实现财富公平分配，缩小贫富差距是宜居城市包容性增长的重要体现。

（2）请你从《经济生活》角度，说明城市实现财富公平分配、实现包容增长的措施。（6分）
