As long as land has different levels of productivity it's impossible to not make housing an investment. The only solution are exponentially increasing taxes on land, in order to ensure that land usage is always used in tandem with the potential productivity (which has its own issues), or make most housing nationalized like Singapore. In the end, for better or for worse, the issue is a dissonance between the struggle of renters and political activity. Homeowners do not make up the majority of the electorate (though interestingly the majority of households "own" the household in which they reside). You'd think that renters would the laws in their areas reflect their will, but alas, renters have low voter turnout.
