I guess universally the poor are blamed for being poor.
Here it's the other way around. The poor seem to be excused on the grounds of 'misfortune' whilst the rich are crucified. Our society seems to be geared towards resentment of the rich.
I can see where both sides may be overstating their perceptions and making blanket statements about "the rich" and "the poor," while most of us probably fall somewhere in the vaguely-defined "middle class" or "working class" as it may be known in other countries. But it's overly simplistic to generalize about the poor, since the lower classes don't all fall into the same category or grouping which can be easily summed up as "people who made bad choices."
I don't know that the rich are necessarily "crucified," at least not on a mainstream level. A lot of people glorify and envy the lifestyles of the rich and famous, especially when it comes to celebrities, rock stars, and even royalty. Likewise, many of the anecdotal "rags to riches" stories which dominate mainstream propaganda are generally glorified and given positive attention. Heck, even the guy who invented the Pet Rock is remembered fondly, although the suckers who actually spent money on that silly thing - that's a different matter.
But the historical record also shows that not all who became rich did so under honorable, peaceful, ethical, or lawful circumstances, and in those situations, there might be negative attention and resentment.
I don't think very many people blame
all the rich; I think the real focus of resentment is against those with power and others who use knowledge of the system for unscrupulous gain.
When it comes to the poor, I think distinctions should be made between those who are genuinely lazy, criminal, or otherwise dishonest versus those who may be truly disabled, mentally ill, or some other malady.
Then there are those who may work at a low-paying, menial job, yet they're still working an honest job, following the rules, and doing what they can to be good citizens contributing to the value of their community. They don't deserve to be treated like dirt or lumped in with bums and welfare chiselers.
So, yes, you're right that there's resentment of the rich, but also resentment of the poor - not to mention other levels of resentment overall. It's clearly having an effect on the level of political gridlock and divisiveness taking place. The politicians and pundits will continue to stir the pot, as they need their jobs as well.
