It isn't that I, personally (thank God), am in dire straits. Thankfully, I bought my home in the '80s, it's paid for, and the only increases I watch for are utilities and insurance and the cost of maintaining it. I do most of that work myself.
But I'm looking at three generations following me who are struggling, partly because of individual decisions, but also because that dollar just does not stretch as far as it once did. I've learned to shop loss leaders, stock up, how to avoid retail prices, but this is a skill that just isn't being picked up by a generation (or three, actually) who will buy at convenience store prices when they could have, with a little planning, had much more for less.
Being willing to say "not at that price" and walk away from something I'd like to have helps, and that's a level of discretion I have had trouble communicating to generations used to having it now, whatever it is.
Buyers can affect the market by doing the one thing buyers can do--withholding purchases until absolutely needed, deciding on a price point above which they will not go. Unless you are planning on moving on, paying rent is what will keep you poor, but with rents where they are, it's tough to put together a down payment and build equity.
I'm not sure that has really changed, though, it was tough to put together the down payment for this place when we did. It involves a sense of planning for the future, of some austerity today for the promise of tomorrow, and that's hard to do when the Government keeps flooding the economy with dollars, diluting the value of any savings.
Note, too, most of the people advising on investments are starting with $100K, while the people who really need the advice are hard put to squeeze $100 out of their budget. Living hand to mouth is stressful and difficult, but with some adaptation, with the concept that having 'enough' is truly enough, instead of living as large as you can and impulse buying, those on the bottom could possibly do better.
And we haven't talked about the effect of flooding the housing market with an extra 20,000,000 people who aren't even supposed to bee here.
