Sounds like you’re well paid and your time is valued, I imagine most devs would be happy with that!

My understanding with phones is that you phone your own provider, who then looks up the provider of the number you’re calling based on country code, provider or area code prefixes. Providers will “peer” with each other to route calls over the most cost efficient path. So the other sides provider is responsible for getting it to the right destination phone within thier own customer network. Theres no authentication from the sending party on a protocol level, this is why scammers can spoof as any phone number.

I believe that IP routing does something similar, the IP data is handed over to possibly multiple providers until it reaches its destination provider. The blocks of ip addresses are published as linked to an Autonomous System and each autonomous system has an owner/provider. The source is not authenticated at a protocol level which is why we need client and server certificates.

In DNS you go to the root TLD servers and ask what IP the .com resolver is. The .com resolver has a list of mappings of authoritative name servers to domains. So example.com may have an authoritative NS of 1.2.3.4 who you can go to and ask what IP test.example.com is hosted on. The authoritative name server is the source of truth for that domain and other servers cache it to prevent overloading and increase speed. You may check with the authoritative NS if you want, but it may be slower to respond than your local NS. Again DNS is not authenticated at the protocol level so we need server certificates to prove that the device behind the IP serving you is allowed to serve you test.example.com.

You’re probably right about being worse off overall, just so much unnecessary complexity. We do have council tax here, but that depends on how big a house you live in and how expensive the area is to maintain for the council. And its a fixed rate per household, owed monthly while you’re at the same address. But I know the councils get most of thier funding from the state budget and other income streams like selling land. Theres also national insurance too which I guess is like social security. https://www.gov.uk/national-insurance

I have no idea ehich one is better, or costs more, but the UK does seem to offer more in return. Admittedly I only see the bad news stories about the US so have no idea what its like “on the ground”. I’ve been to Florida, New York and Vermont, so I see how states are very different places with different needs, understandible why theres not a lot of state unity on issues.

The UK also has much higher income taxes. Comparing US and UK income taxes:

• in the US, for someone earning 578,126+ USD (£457,000) it’s 37%
• in the UK, for earnings over £50,000 (~65,000 USD) its 40% , equivalent US earners only pay 22%
  • and when over £125,000 (~157,000 USD) this increases to 45% in the UK

US income tax is ferarally controlled. I don’t have exact numbers but increases in income tax for the highest earners should be able to fund a public healthcare system, at least for the lowest earners in the US.

Edit: There are also state income taxes, which vary for some reason, I’m sure theres also county and city based taxes as well, processing them must be a nightmare. Is the US just 52 countries in a trench coat?

In the UK you can invest £20,000 (25,000 USD) per year into a fully tax free ISA savings account. You can spend it on anything you chose at any time, and you will never need to spend any of it on healthcare against your will. https://www.gov.uk/individual-savings-accounts/how-isas-work

Dental care is free in the UK for under 18s, people who are pregnant or given birth in the last 12 months, or people on low income. https://www.nhs.uk/nhs-services/dentists/who-is-entitled-to-free-nhs-dental-treatment-in-england/

Also if you were to unfortunately become disabled and are unable to work, you will be supported fully for the rest of your life. These benefits are not based on previous taxes paid like in the US. https://www.gov.uk/financial-help-disabled https://www.gov.uk/pip/how-much-youll-get

This is wild, in the UK, if you were in an accident and needed years of surgeries, it will always be free. The cost of parking to visit the hospital will be the most expensive thing anyone ever gets billed for, and that will be around 10 dollars a day. We do pay income tax, but lower income earners pay less or none. Theres also sales taxes, and things like sugar, alcohol and nicotine are taxed quite highly as they can contribute to health problems. But it’s all well worth it to never worry about medical costs. https://www.gov.uk/income-tax-rates https://www.gov.uk/government/news/sugar-tax-revenue-helps-tackle-childhood-obesity https://www.gov.uk/tax-on-shopping/alcohol-tobacco

Serious question, wouldn’t it be cheaper to buy it?
