ELI5: Wages are supposed to rise with inflation. Does that mean wages will just rise infinitely?

So we all know the cost of living has gone up a ton. I'm in my 20s and I feel like all I've know is inflation. I did some googling, and found out that deflation isn't ideal and instead wages should rise to meet the cost of living.

So that got me wondering - are wages just supposed to rise infinitely? For example (with made up numbers), let's say the average monthly food shop was £500 in 2000 and that was 20% of the average monthly pay. In 2020 the food shop is £1000 but wages haven't risen by much, so it's now 30%. Less money all round.

So it seems to be better for said food shop to go back to being 20% of pay rather than going back to costing £500. But what would be the limit? The food shop being £5000 but still 20%?

Numbers get bigger over time. In 1960, nominal prices were about 10x lower than today. There's no limit and no real reason to care.

To be a little more clear, for your standard of living it matters how many goods and services you can purchase with an hour of work, not how big or small the numbers on your paycheck or the grocery store bill are.
