On the one hand I'm already pulling a decent salary, $155k, and I've been consistently raising that number in the last couple years.

On the other hand, I recently married, and I might have kid(s) in a few years. My wife is in a low-paying profession. I'm having a hard time imagining how to raise it any further. Specifically, how to double (and then quadruple) it.

I'm a proficient JavaScript engineer working remotely from somewhere cheap, so living expenses aren't a concern for me (as opposed to someone living in, say, SF or NY). I have a good job at a good company, but I would jump for, say, a 20% pay bump. I have done so in the past and it works pretty well.

Do I move to management and forget all about coding? Is this worthwhile? Is there money to be made or will I just loathe myself for making the switch and barely make more money than I am making now?

Do I learn about investments? I read index funds are one way to earn money. There's also private investing, etc. But I know literally zero about any kind of investments.

Any and all advice will be appreciated!
