High inflation will have knock on effects in which consumers will eventually stop buying items, instead focusing on the bare essentials either out of fear or actual cost cutting needs.

This reduction in spending will largely affect non core spending like services and luxury-ish/luxury goods like electronics, cars, houses, etc. This happens to be where the bulk of the US economy is focused which means a slow down in spending there will effect workers in those industries.

Couple that with higher core good costs and just natural momentum in regards to spending. You're left with large parts of the economy that experience a flywheel effect that make it harder to purchase things and further reduce the ability to spend on other non-essential goods and even when things start to change, peoples mindset on spending takes years to shift with it.

All of this leads to reduced demand and ultimately a recession.
