That's many questions. Lunokhod 2 lasted for nearly 4 months and held the record for longest distance traversed by an off-Earth robot for over 41 years, until MER-B (Opportunity) beat that in mid 2014, so I wouldn't really say that lunar rovers don't last. It eventually scooped up some regolith dust with its open lid that was also its solar panel, and as it closed it to prepare for lunar night dumped dust over its radiators and overheated. But it completed its mission.
Otherwise, we didn't send more rovers to the Moon because it was for a long time after Apollo program considered veni, vidi, vici, and only became more interesting again after NASA's Mini-SAR on Chandrayaan-1 found evidence of South polar water ice. Sure, you know the phrase, The Moon Is a Harsh Mistress, and there are certain challenges with robotic exploration of it (talcum powder fine dust and its dielectric, photoelectric and triboelectric properties, long nights, high diurnal surface temperature swings and difficulties with cooling during days and heating during nights, harsh and often highly inclined terrain covered with impact craters and debris, half of it not in direct line of sight with the Earth, difficult lighting conditions with backscatter at high noon, other times long and incredibly contrasting shadows, radiation,...), but other destinations have their own sets of challenges, too. That's not the reason you can't observe recently taken snaps off the lunar surface (tho you can those taken from its orbit). Simple truth is that since we established that the Moon is a barren rock with no immediate utility to our exploration of the Solar system, our attention focused on other celestial bodies and the search for conditions for life, and soon more direct search for life where we think conditions for it might exists.
But we'll go back. Actually, any self-respecting space agency has now plans to send rovers on the Moon, with its South polar regions being of most interest, of course;
JAXA plans SELENE-2, ISRO Chandrayaan-2, China Chang'e 4, NASA Resource Prospector and running a couple of other programs at various levels of maturity, ESA is working on comprehensive lunar exploration plan under the umbrella of the Aurora programme and currently cooperating with Roscosmos on PILOT, SPECTRUM, PROSPECT programs that go from precision landing platforms to sample return missions, and so on. And there is a large number of private ventures with interests in mining the Moon for its resources, and/or to use it as the staging ground for more distant destinations or to service near-Earth / cisluar operations.
To get a bit better perspective of upcoming missions, here is the current (prepared for the currently ongoing LEAG Fall 2015 meeting) International Cooperation and the Global Exploration Roadmap:

Exploration Team Directorate of Human Spaceflight and Operations. Source: ESA's plans for Lunar Exploration
Many of these missions include lunar landers and rovers. In fact, there's more lunar surface missions on this roadmap than, say, Mars surface ones. So your question might be, hopefully, short-lived and in a couple of years time, someone might even ask why is there such an apparent overpopulation of robots at and around the Shackleton crater. :)
