I find that a lot of the "big" issues boil down to trust - in businesses, in Wall Street, in the government, in the justice system.
If one person's POV is that <institution> should help while the other person's is that <institution> can only hurt, then they are never going to agree no matter how many links and memes and snarky comebacks they throw at each other.
This point cannot be emphasized enough. I have encountered people on the opposing side of an issue who have stronger critical thinking skills than people who I agree with (and probably even myself). The differences come about due to a differences in the foundations of our knowledge or on pivotal points where neither side can claim to have an definitive answer.
