In general, countries with high real gdp per capita also received "very high human development" or "high development" rankings from the united nations. so, how do the two measurements compare?

The GDP is representing the total production in a year in a particular country of all final goods and services. The GDP per capita on the other side represents the amount of money that the citizens have on average, thus their financial strength. When compared, these two can show totally different pictures, or they may show very similar ones. Some nations do have high GDP and also high GDP per capita, while some have very high GDP , but the GP per capita is average or even low. We can take the UK and India as examples. They have relatively similar GDP's, but when the GDP'c per capita are compared then the UK is light years ahead. One of the biggest reasons for this is the population, as both countries have similar GDP, but the UK has around 20 times smaller population than India, so when the money are redistributed on the amount of population the differences are enormous.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
