We DO have very low cost consumer goods. Most of it's crap and breaks in a few years, but it is certainly cheaper than ever. Clothes are basically free, electronics are super cheap. Appliances and furniture are pretty cheap.
The only things going up signficantly in cost are:
housing - driven by government regulation, artificially low interest rates, and a large labour component in construction
automobiles - seemingly driven by government regulation, but also by artificially low interest rates that have allowed feature-itis. Automation is widely used and you would think there would be low cost cars around as a result, but instead we get expensive tanks with 8 year loans.
health care - huge labour costs, resistance to automation. In my country it's all unionized government labour too, which means the cost growth is practically unconstrained. In the US, cost growth is driven by monopoly practices that would be illegal in other industries and cost-shifting to third parties
education - all labour costs. Also artificially low interest rates and government regulation of student loans has made large amounts of money available to people who shouldn't qualify to borrow anything. That in turn has enabled schools to siphon off all that borrowed money. Universities and bankers get rich, students get lifetime debt servitude, what's not to like.
energy - well, we're running low on cheap fossil fuels. Not much to be done about that. It's tough to improve on "stick a pipe in the ground and free energy flows out".
Basically, any industry with a large labour component, or which experiences heavy regulation, or worse, both, has become increasingly expensive relative to how cheap everything else is becoming. Financialization and the suppression of interest rates have enabled that growth.
Labour gets more expensive as taxes get higher, and taxes get higher as more people lose their jobs or move into much lower paid work where their health care or transportation costs are subsidized by those still working higher paid jobs.
