Wishful thinking gets us nowhere. Real answer.
"The Page Act was supposed to strengthen the ban against “coolie” laborers, by imposing a fine of up to $2,000 and maximum jail sentence of one year upon anyone who tried to bring a person from China, Japan, or any Asian country to the United States “without their free and voluntary consent, for the purpose of holding them to a term of service”.
However, these provisions, as well as those regarding convicts “had little effect at the time”.
On the other hand, the ban on female Asian immigrants was heavily enforced and proved to be a barrier for all Asian women trying to immigrate, especially Chinese."
Due to the Page Act of 1875 it became incredibly difficult for Asian women to migrate to the USA as they were seen as "corrupting white men" as many worked in prostitution.
Among Asians genders only reached parity after WW2. To give an idea of how serious the gender disparity was between 1946 and 1952 almost 90 percent of all Chinese immigrants were women and only then were the ratios Asian male/female ratios close.
TL/DR: The only reason there were more Asian guys with whites back in the early 20th century was because of the complete lack of Asian women. It was like winning a race without any other competitors.
Once there were Asian women, the familiar pattern happened.
