Be careful when trying to draw conclusions about cultural values of different ethnicities within western countries with high percentages of recent immigrants. Immigrants in general outperform natives in income mobility, and this tapers off in later generations. Additionally it's difficult to ignore the massive selective bias within immigrant populations. Immigrating is very difficult and that's positively reflected in basically every way you could measure the character of those populations.
In America immigration isn’t difficult at all—we don’t have skill based immigration. The Asian kids being raised in the bottom 20% of the income distribution are mostly here based on chain migration.
