From the 1930's until now, sociologists have found that the mental health of the lower classes is worse than that of the higher classes. one explanation for these differences is that the poor

The poor have less money than the higher classes, which makes it more difficult to keep up with bills etc. This may force them to work more often than someone of a higher class, and put more stress on their shoulders because of the risk that they might lose their home or other possessions. The constant struggle to support themselves or their family can cause mental health issues, like depression.

Is this a question? But yea
