Well latinos and asian immigrants come from two different stocks. Most latinos like you said are poor immigrants. While most asians that immigrants are either professionals or had money.
I'm Asian bro. I know how poor the first generation Asian immigrants were. My parents told me stories about their childhood. They couldn't afford to eat meat, or even eggs. They didn't have money. They struggled with language barriers in the US and got engineering degrees. They overcame a bad environment.
If you think colonialism built any sort of infrastructure in Africa you need to do more research. Colonialism built ways of extracting resources and nothing more.
Ghana in the 1920s when Governor Guggisberg was able to fund the creation of what became the country’s best-known hospital and school, as well as a new harbour and more railways and roads, from customs proceeds that had been fuelled by the colony’s increasing exports of cocoa beans.

There are entire histories and courses of events that can explain why china and japan and south korea and singapore and hong kong and blah blah blah didnt for one get treated like africa and two were in africas place at the start of colonization. But if you want to ignore mountains of evidence and want to be lazy and just say, hur dur, its because of their skin, literally the most insignificant part of any person than be my guest bro.
The Japanese treated the South Koreans just as badly, if not worse, than the Europeans treated the Africans. South Koreans were mass-raped.
I'll quote myself.
OK let's find something more comparable. Japan colonized South Korea, treated the country just as badly if not worse than the way the Europeans treated the Africans. The Japanese immigrated to Korea and took the land, became the local ruling elites, etc. Korean farmers lost ownership of their land and became serfs overnight. They had no need for an indigenous elite, they imported administrators and business managers from the homeland wholesale. South Korea was poorer than the Congo and Zaire in 1960.

From around the time of the First Sino-Japanese War, Japanese merchants had been settling in towns and cities in Korea seeking economic opportunity. By 1910, the number of Japanese settlers in Korea reached over 170,000, creating the largest overseas Japanese community in the world at the time. The Japanese leadership's conviction that their country was overcrowded – especially in rural areas – led to encouraging farmers to emigrate.
Japanese landlords included both individuals and corporations such as the Oriental Development Company. Many former Korean landowners, as well as agricultural workers, became tenant farmers, having lost their entitlements almost overnight.
They took all the land and turned Koreans into slave laborers. South Korea is a thriving first world country today.
