You'll definitely have a positive effect on people by teaching them about western business practices. I'm told by my former coworkers that my standard US egalitarianism was quite unusual. By "egalitarianism", I simply mean "I'm CTO, you are a mechanical turk, we can go eat pancakes and you aren't obligated to make me tea". So were my efforts to ensure that everyone was growing in their career. My feminist sensibilities ("so be late, tell your husband to make dinner") were also a bit scandalous [1].
I came back to India a month ago to attend the wedding of someone I worked with, and I was very surprised to hear all that. I don't know whether to be happy (I made things better) or unhappy (because their next job won't be so good) about it.
By building a good business and maybe destroying some bad local ones, you'll do far more good than you will by doing unskilled construction labor. And very importantly, the people who work for you will learn that western style management is a great way to make money.
[1] By US standards I'm one of those evil misogynists who thinks statistical disparities are irrelevant and discrimination is a testable hypothesis and market opportunity. But drop me in India and I'm suddenly a crazy feminist ranting against rape culture (FYI India has one, the US doesn't).
