You were wrong about bonus tax rate

1.  "我在网上查了一下，属于奖金的收入需要缴纳百分之四十的联邦所得税"

Wrong.  bonus (supplement income) is taxed at 22% for federal income tax.  

Your company withheld $390 for federal tax out of a total payment of $1775.  That's 22%.

Most of your other statements are equally misleading. 

2. 咱这二十五年为万恶的资本主义社会做了多少贡献啊。辛苦劳作的工薪大众挣来的钱都被用来救济穷人、付军费、盖监狱，美国政府还在哭穷，

救济穷人 is socialism, not万恶的资本主义社会.  

Pay your fair share.  Both Brooklyn bridge and helipad for Trump need your tax money.
