Before giving a very short answer to the question you asked, so on this occasion I will give a little example for the question you asked where I, who earn as much as $70 per week through the signature campaign that I am currently participating in, can still make money. a small family that I have now in the country of Indonesia. And the answer to your question is "There is" in Indonesia.

The $70 per week I get from the signature campaign that I now participate in is around Rp. 1,036,000 if it is cashed into Indonesian currency and that is quite enough for someone who is married and has a small family by spending Rp. 145,000 per day or about 10$ per day because the staple food and drink where I live today is still so affordable and not so expensive that it's still very possible for me to still live on the income from the signature campaign.

And for those who also live in Indonesia, but are still not married, I think the cost of living is still much smaller than for married people so the amount of income he gets from the signature campaign will be much more than enough and even part of it can be made for savings life for himself. Especially if you refer to the example you gave with $1500/week, that is already very extraordinary for those who live in Indonesia.
