Lucrative and secure are in tension only if the work is also very interesting (or fulfilling/challenging/stimulating, etc.)
If a job is all 3 of interesting, lucrative, and secure, then everyone will try to get that job, and the competition will either drive the salary down, or drive the job security down, or both.
A more general version of this rule is that anything desirable (or "scarce" if you want to use an economic term) in life will soon be pursued by others to the point where it becomes no longer desirable. That's the essence of how markets work.
The trick to wealth is to know (through some combination of vision and luck) what is going to be desirable ahead of time and obtain it before everyone else knows they want it.
