When I saw this I felt that.....
It shows the inequality of the world, which Christians are well aware of and clearly have not done enough to solve the problem.
This meme is represents the western Christian, someone who MAY help the less fortunate but probably doesn't because there wouldn't be so such suffering in the world.
So the process of thanking your god for your amazing dinner is demeaning, shameful and wretched, to those in so much pain and suffering.
Finally, who's to blame, god or his followers?
I think a lot of this represents the profound disconnect between the opulent, insular West and the far less affluent developing world. We're disconnected by distance, geography, and geopolitics - among other things.
Whether or not people are "doing enough to solve the problem" is itself a difficult question to resolve.
The Christian family in the picture thanking God for a nice meal is thousands of miles away from where those starving children might happen to be. If those starving kids were right outside their front door, I'm sure they probably would have taken them in and fed them. But since they're so far away, what can they do, realistically?
These are issues that have to be decided by governments, and in the case of the Western democracies, "not doing enough" could be defined as not supporting the politicians who have political views directed towards solving these and many other such problems facing our world.
I would defer the question of "who" is to blame. I would say we're seeing the consequences of conflicting values and various forms of ideological intransigence where people become somewhat arrogant and overconfident into believing that their way of thinking and their ideological faction is better than others.
So, rather than make any honest effort to reach a solution, many people choose to fight whatever they see as "enemies," "unbelievers," "deplorables," etc. This is especially true in many parts of the world which have been heavily exploited and political unstable, susceptible to civil war, outside agitation, and/or military coups. It's in those kinds of situations where we see most of these horrific, tragic pictures of starving children.
If there is a God who created all of this, then one might observe some design flaws which, hypothetically, could be blamed on the "designer," if there is a designer. Barring that, then, yes, it is a human problem that has to be resolved by humans.
