Of course life isn't easy; people just don't help each other. I could easily produce 10x than what I'd need to survive but there isn't a point to do that when I only get paid enough to live off of. We can work together to out produce our needs and then give the leftovers to others in need. It's not fair being stronger than other people, yet weak to help them out.
Not everyone is equal, some can produce less, some aren't as smart, there's so much varying factors involved that it's impossible to decipher what is best for this world. I do know that what we are currently doing is wrong because a large percentage of people are living in poverty sifting through our trash to produce goods when we can easily build factories or schools for them to thrive. It's not hard building a house; the problem is knowing how to build one and having the correct materials to do so.
