We live in a capitalist economy, at this point it is absolutely dominated by finance and speculation rather than real growth and production, and it is pretty hard to survive long term without investing, particularly if you ever want to buy a house. House prices tend to rise faster than inflation, so you're losing on both inflation and appreciation. I don't think this should be the way it is, but it is the way it is. House prices and the rental market are linked by future cash flows so there's no escaping it unless you are homeless.
