When we look at the entire world population, I do think things are changing but I think it is really, REALLY slow going.
Some changes are slow. Especially in nations with little freedoms. Other things are changing very very fast. Technology, information, etc. Who ever thought we might see newspapers diminishing and that we had access to the information we have at most of our finger tip. In the US, Europe and other developed nations many of the poor are still more comforable than most humans through out history.
While in the US (and in other developed countries) we have people who can "move up" the economic ladder, I don't know how many people really move dramatically up. I'm guessing most move up a little, one rung on the ladder, (smile). However, if we look at the rest of the world, the cast system is still alive and well, and there is little opportunity for most people to make dramatic changes. (I think).
I think many move way up and fast. Look at what the average American owns compares to our parents then compare it to their parents. There have been great leaps at least in creature comforts and material wealth. Course that may be disappearing if our economy crumbles.
I was actually thinking today how really similar we are to the various hierarchical or stratified levels of society that have existed throughout history. The names, laws, and some of the dynamics have changed but they are pretty much the same as they have always been.
I strongly disagree at least in the nation you and I live in. Other places yes.
The rich get richer, they get an education, make the laws, run the town/country/state/religion, have the control and power. The poor work, and play their role in society.
Everyone has opportunity in the USA. Anyone can move up the ladder and some rapidly. For some it is easier for others harder but they can move. And almost any American can get a college education if they want it. There is plenty of help if they don't have the money and there are still state schools that are affordable.
Another thing, in terms of the end of the world and signs of the times, is an economic crisis even on God's radar How about global warming? What difference do these types of problems make to God?
Personally I think the idea that global warming is man made is far from proven and more likely than not we are coming out of a rather cool period in the earth's long history. That said I am still all for doing things to reduce carbon emissions, renewable energy and caring for our environment. As for economic issues? We may not like what is happening but it is nothing new and has happened many times before and even in our life time we have had some rough recessions and one that was I believe worse than at least where we currently are in the late 70s and early 80s. We may pass that one yet, but not yet.
