美國人口結構的趨勢就是黑墨化。再過30年，白人就是少數民族，黑墨將接近一半。到時美國會是什麽樣呢？
別的不說，先看看各族裔高中畢業生的sat數學平均成績吧：黑人 428， 墨裔 457，白人534，亞裔598 （注意sat 起點分數是210分左右，一個亂填空的猴子大概都能得個二三百分）。這個平均分的差距幾十年基本沒變，所以不難得知當黑墨人口增加到幾乎人口一半時，美國的人口素質會是什麽樣子。
不同族裔sat成績的差距一直縮小不了，AA也就取消不了，可以想見的是隨著黑墨人口的擴大，在大學招生以及高薪工作領域，亞白會受到進一步擠壓。比如現在有左派思想庫學者就提出大學取消sat成績而隻看GPA, 矽穀公司也要求擴大黑墨員工比例。。。。。。
所以，茶黨崛起和床鋪當選，本質上是白人對美國黑墨化的抵製。而因為白人不生，同性戀猖獗，黑墨化的趨勢是阻擋不住的。 看明白這點，不難想象今後20年會是美國保守派（包括種族主義者）試圖反撲的的時代，而愚蠢左派的行為 （比如伯克利騷亂，比如這種BLM的抗議 https://www.youtube.com/watch?v=Mv0nVI2rI0Q ）都會加速白人對民主黨和黑墨化的抵製。
作為華人，盲目維護和支持美國極端種族主義白人所支持的床鋪或是站在支持黑墨化的左派一邊都是愚蠢行為。

這是美國左派思想庫新出爐的關於sat的報告：
The SAT provides a measure of academic inequality at the end of secondary schooling. Moreover, insofar as SAT scores predict student success in college, inequalities in the SAT score distribution reflect and reinforce racial inequalities across generations.
The mean score on the math section of the SAT for all test-takers is 511 out of 800, the average scores for blacks (428) and Latinos (457) are significantly below those of whites (534) and Asians (598). The scores of black and Latino students are clustered towards the bottom of the distribution, while white scores are relatively normally distributed, and Asians are clustered at the top:
Race gaps on the SATs are especially pronounced at the tails of the distribution. In a perfectly equal distribution, the racial breakdown of scores at every point in the distribution would mirror the composition of test-takers as whole i.e. 51 percent white, 21 percent Latino, 14 percent black, and 14 percent Asian. But in fact, among top scorers—those scoring between a 750 and 800—60 percent are Asian and 33 percent are white, compared to 5 percent Latino and 2 percent black. Meanwhile, among those scoring between 300 and 350, 37 percent are Latino, 35 percent are black, 21 percent are white, and 6 percent are Asian:
These gaps have a significant impact on life chances, and therefore on the transmission of inequality across generations. As the economist Bhashkar Mazumder has documented, adolescent cognitive outcomes (in this case, measured by the AFQT) statistically account for most of the race gap in intergenerational social mobility.....
....
There are some limitations to the data which may mean that, if anything, the race gap is being understated. The ceiling on the SAT score may, for example, understate Asian achievement.
