People won't go to the GP for minor issues - they will then become major. Someone leaves an issue till they have an emergency and then have to get an ambulance, A&E and a long-term hospital admission which costs more than the initial issue. Also disabled people will be discriminated against, already many struggle with paying for medication (in the U.S - think about how many struggle with drug addiction and don't get help, think about how in a vile of insulin often costs around $10 but is sold minimum at $90.* *
Then there's the class discrimination. What about the 4.5 million in child poverty, those kids won't see doctors. What about BAME populations more likely to live in deprivation? Also women, particularly single mothers, postpartum? Their mental health will likely worsen, they won't be able to sacrifice food on the table for the doctors - so they will get sicker and it will cost more in the long-term. What about the elderly (yes some are well-off) but othera are very poor abd have nobody to look after them. There's so much research on why this would 1. Increase health inequality massively 2. Cost more in the long-run 3. Lead to more overall inequality and deprivation in communities in general e.g lack of advice on alcohol or nutrition in these communities. You can say only £20 (but would that even be enough, and then the price will just get higher). Right now GP's get on average £110 per appointment. So will it be that much. Also for loads of families £20 per appointment will be too much, they are barely eating or not paying bills.The only reason paying for face to face appointments will free up appointments is because those who cannot afford it but still need care and are sick won't be going. So yes you'll probably get an appointment quicker, because you can pay and some people (who may need an appointment just as much as you or even more) cannot.
What if (as many do worldwide) they have to ration medication such as insulin or HIV meds? The distribution of appointments should be solely down to need, i.e triage - which many GPs do. Who is that more likely to be? Those in deprived communities, we know they have poorer health outcomes, more SEN, more mental health crises.
What's already costing a fortune is the lack of acess to free care which we see in dentistry - Wes Streeting said a couple weeks ago that the number 1 reason for kids admissions now to Alder Hay Hospital is tooth infections and tooth issues because these kids aren't seeing dentists as their parents cannot afford it - and those very skilled doctors aren't spending that time on complex care.
Yes the middle-class is being squeezed but that's not because of the working-class, maybe focus on the millionaires and billionaires, and the owners of companies that don't pay staff well, or the water companies increasing bills when they pour more sewage into water. Also those with children, elderly, disabled, poor are also (like the middle class) being punished. They are working multiple jobs, but landlords keep increasing rents to ridiculous prices, so they are often getting evicted, or sharing 1 bed room with 2 kids and the parent. More and more schools now have to wash children's clothes and get them beds not because these parents don't love their children but because they cannot pay the electricity bills so don't do as many washes. People can fall on hard times, suddenly the rents too high, and then your homeless. Or you get pregnant (maybe your in an abusive relationship, or struggling with substance abuse) and then the child suffers because of who they were born to? Missed appointments are a problem and I think measures should be put in place to deter this - I know many services will cancel your referral if you don't attend.
Look at the amount of people in the U.S with thousands and hundreds of thousands of medical debt. Which impacts credit score and from there many other things. I just think once you start even if it's £30, what do companies (insurance) love to do - break things up. So over time it will be £30 to go to A&E, (just for sitting there), then extra maybe a couple hundred or a £1000 for a scan (MRIs are expensive so they'll be higher than an x-ray or ultrasound). People will refuse scans that they need because of the cost. Then they'll you more for overnight admission, and more and more.
I fundamentally disagree that people don't value a free service many people I know and myself included are so thankful for a free service otherwise we wouldn't have gotten treatment, maybe wouldn't have finished school if we couldn't get medication. Especially those who are of lower socio-economic status, because they know they can't afford it and value care.
