Construction work, plumbing and mining (for workers) are not well paying industry when compared to software. Also, these industries are male dominated because they require hard labour and working conditions, which is often biologically unsuitable for women. Even then, in South Asian countries you can find even ratio females to males in construction work. They do the same hard labour as men, and as the use of machinery and automation is rarer (in these regions), it's even more manual hard labour.
