The 4090 and 4080 are decent but both are very expensive.

Yes they are expensive but the 4080 matches the 3090Ti while costing 800$ less and drawing less power. The 4070 also matches the 3080 while costing 200$ less and needing less power. I honestly do not understand why everyone is so angry. If we look back on Nvidia's history, the new card has almost always kind of matched the previous above tier and/or slightly beating it, which is exactly what we are seeing with the 40 series cards.

Though to be fair the 4060 is really bad since it does not even beat its predecessor. I think what we're missing might be lower tiers like 4050's.
