Like diapers, politicians become dirty and need to be changed. I don't think drastically longer terms are a solution. Systems with proportional representation tend to be much less susceptible to this, as a few seats changing won't tip the balance from one extreme to the other. I have no idea how such a thing could be enacted though, as legislative power is in the hands of the two parties that would be the major losers in a switch away from FPTP.
