Hanging out with low class people [in terms of "Midot" that is traits like honesty, compassion etc] tend to damage one's own traits. I have definitely not been careful about this myself partly as result of naivety, and partly because in the USA it is considered that all people are equal. So I did really not get an idea of dividing people by traits.
But for myself, now I can see in retrospect that it should have been easy to identify groups that I could have avoided by simply being aware of the difference between groups that excel in traits and those that do not. The difference is obvious if you look for it.
That is to say I see "midot tovot" [That is what is called "being a mensch"] as being the main key to Gan Eden. Another way to look at this is simply to fulfill the Ten Commandments.
However the Rambam did add to this in הלכות תשובה that one's portion in the next world also depends on his wisdom.
