Depends on the country you are from, but from my perspective this would be almost impossibe. On the other hand if you have very good paid job and some funds to invest and you don't need to spend much then it's possible.
Depending on you're country this is far from impossible. Here in the US you'd be living on the street if you could only get 10K a year. It really varies from country to country.
I agree with you. But everyone has the opportunity to earn on the Internet. And here there are no borders. The main thing is a person's desire to make life better.
Yes but in order for one person to make some serious money on the internet, one does need to have either some specific skill set or enough money to start trading or something like that. What can person with some common skills like automobile repairing do online... well nothing. So its same like in real life, you need to have something to trade it for what you need. If you don't have anything to offer, well than you will get nothing... its simple.
