@jklmd123 Some education certainly has high return. You can't even do a very good job of being a landlord or plumber if you can't read or do basic math, and you can probably do a better job with some level of understanding of economics, marketing, law, etc.
@jklmd123一些教育肯定有很高的回报。如果你不会阅读或做基础数学，你甚至不可能做好房东或水管工的工作，如果你对经济、市场营销、法律等有一定程度的了解，你可能会做得更好。
