Earlier a single bank had billions of dollars but now all the dollars is in the form of land/buildings which is not worth that much. A single bank holding billions of dollars got diluted leading to the liquidity crisis and started to fail one next to another. Meanwhile there were job loss making the consumer cautious about the future hence lowering the confidence level in spending. So there are new phones in the market but no one to buy, new furniture's but no one to buy so on and so forth. This exposed all the tech companies, infrastructure companies etc to the sub-prime crisis which was no way fault of theirs but that is nature it takes everything along with it.
But is it the time to worry? not at all as this might have a catastrophic effect. Time is still not far, it might very well lead to a humanitarian crisis since many people are out of jobs and hence adequate actions must be taken.
It is not the moment to worry rather it is the moment to take this crisis as an opportunity and show the true talent and be a leader leading the world to come out of it. I always believe there is nothing challenging to raise the profit level from 10% to 12% but it requires a courage, it needs a dedicated individual, it needs the spirit to believe that nothing is permanent: rise and fall are just nature it is just for the individual to decide when to board the bus and make sure to drive the bus to the destination.
Economic crisis is not an end it is just a beginning which shows us the future....
Seeing sunrise or sunset is just a perception as the sun never rises nor sets.....
