Re: Is there a place in the world you could live like a king via sig campaigns?
I think it's not possible to support an entire family only on basis of signature campaign earnings from forum, I mean sure that there are high paying campaigns but the cost to sustain lives is much higher, if you see, specially in developing countries, the average middle class earner earns around $1000 a month and still they live not in a very good fashion. In developed countries the cost to survive is much higher, and I guess it's easier to get a job in developed countries that pays way higher than most signature campaigns here. And it would be boring to live solely on signature campaign money because we should work as it's fun, keeps our mental and physical health good and saves us from boredom 
I disagree bro, In developing countries this amount is enough to leave comfortably with this amount, i don't know how many average middle class earners that earns up to that amount in developing countries, in fact, anyone earning up to that amount monthly lives a high standard life and can easily fends for family without much stress. As you have mentioned already, the standard of living in developing countries are not so expensive as that of the developed countries. In some developing countries, the tax structure is not very strong, with that amount you can do more and pay less tax unlike in advance countries where the tax is very high.
i don't know why you think it will be boring to live solely on signature, it is more like working remotely online, and depending on individual needs, such work can give you the opportunity to do other things that are of interest (assuming signature is a long term job)
