The impact of normalising interest rates is not anywhere near obvious yet. More than 90% of borrowers are either on very low fixed rates or hold enough equity or small enough loans to pay the rates at the moment.
Our choices will always be driven by affordability. If that's going to be problem, better to sell and relocate somewhere affordable because all asset prices are normalising after 15 years of artificially suppressed interest rates. There's no point pretending that the "average" borrower or the "average" lender has benefitted from the artificial rate suppression we've had for 15 years. Neither has, nor was it ever possible to sustain. The worst off are probably people near or at retirement in 2008 who did not have the time to recover financially.
People make choices based on personal preferences. Just because you won't help your children to buy doesn't mean someone else can't. And vice versa. Almost everyone will make their choices privately, because most people can see that the last 15 years was an anomalous time when you were paid to borrow (and still are, for now). But even when inflation eventually reduces, when the war subsides, when we can reverse the over-population or over-extraction of resources beyond the carrying capacity of this planet, interest rates cannot go back to much under 4% over inflation without either credit restriction or central bank suppression (and we can see how well that turned out). Normalising asset prices is the best thing for affordability, not suppressed interest rates.
