Show me your numbers! Are you seriously telling me that there are hordes of highly paid high tech workers living here and moving here, working remote/flying/commuting elsewhere and that these workers will somehow keep the housing mania alive?
In fact, the opposite is happening. The past five years we have seen an EXODUS of highly paid high tech workers from coastal areas to cheaper, more livable cities like Boise, Denver, Austin and even Des Moines, IA. They are making the same salary, because they can work remote and service customers in the big cities the same way they did before, but they are paying 1/5 the price for housing. We have also seen layoffs at Nokia (500+), and multiple other tech companies this past year in San Diego.
