How should you dress for a phone interview?

If you're doing an interview via phone I wouldn't suppose you would need to get dressed into anything specific. If it's going to be a video call, then you should at least wear something presentable  that the camera will see (that means you don't have to wear pants).  

Sorry, if you're looking for some specific answer then I can't help you. This question just kinda throws common sense out there and it's just your job to use it.

Hope this helped ;)

being born in poverty would limit the people's chances, opportunities and benefits.

this happen because of several things, such as:

- poor people tend to gain less access to good education and nutrition. this mean that their chance to obtain high paying jobs would also be limited.

- poor people tend to socialize with other poor people while the rich tend to socialize with other rich people. this means that simply throguh their social circle, rich people would have more business opportunities compared to the poor people.

- rich people tend to have more capital in their disposal. this would benefit them in business since it is far easier for them to fund their business operation compared to poor people.
