I wonder if the progressives ever wondered why so many Chinese students or Indian students could excel in the STEM programs of those top universities? Like we grew up with our parents making less than $500 a month in the early 2000s if we were lucky. Heck, a family from countryside or a small town probably made $200 a month or less. Like we studied English with a couple of cassettes and our English was so broken that we couldn't even clear custom when entering the US. Like our schools lost power every few days, and our teachers printed our exams and handouts using a manual mimeograph machine. Like I didn't even know touch typing before I got into college. Like I thought only experts could use a personal computer and typing "DIR" under DOS was so fascinating. Yeah, we were that poor.
Yet, our teachers did one thing right: they did their job. They pushed us. They did't give up on us. They tried every way to make sure their explanation is clear, intuitive, and inspiring. They designed amazing problem sets to make sure we truly understand the fundamentals of math, physics, and chemistry. They didn't shy away from telling us that we didn't do a good job. They forced us to write essays every day, to solve problems every day, and in general to learn deeply every day. I still remembered the sly smile when my chemistry teacher made sure we could solve the ICO-style multi-step synthesis in organic chemistry.
So, yeah, many of us wouldn't be where we are today if our teachers hadn't pushed hard on us. Equity my ass.
