No thats the reality… Your justb eing naive.
I have multiple examples of people who tried to invest in Pakistan and help, only to be burned.
Imagine tomorrow we expats stopped sending money home. What would happen? You know how much the country depends of remittance.
The best thing to do is stay in the US or where ever, and send money to those back home.
Thats not to say that you cant help on the ground, but like I said. Be prepared for a huge hassle and a huge of amount of stress.
