The most brilliant time for liberal arts students should be before modernization. There was no industrialization at that time. Reading is to be an official. Talented people can be officials, even if they are not officials. Because the technology was not developed at that time, there was no need to go to school to learn technology. However, after the industrial revolution, science and technology have become more and more developed, and you can't work without studying, so science and engineering talents are very useful.
In our time, even in my parents' time, there was a resounding slogan: Learn mathematics and physics well, and you are not afraid to travel around the world. In recent years, especially after the trade war, China has once again strengthened the training of talents in mathematics and physics. Obviously, the first batch of new college entrance examination plans is 3+3, which weakens physics. Later, the new college entrance examination plans were all 3+ 1+2, which made physics and history compulsory and strengthened physics. Later, a course selection guide was issued, which strengthened chemistry and basically returned to the old road of mathematics and physics.
In addition, China is very eager for talents in science and engineering, and has given a lot of support to outstanding research leaders in science and engineering, while liberal arts talents have no such treatment.
There are many jobs for liberal arts, such as teachers, banks, investment consultants, accountants, translators and advertising designers.
