Brit here, I've never been to the states so can't really compare, but I'll try...
Pros
- Average work week is 40 hours, permanent jobs come with employee rights like paid holiday leave (around 25-35 days a year for full time), sick pay and they can't fire you without good reason or redundancy pay. Overtime is usually paid at x1.5 or double time.
- The NHS is good for emergencies but not so good for routine treatment, but middle and high paying jobs usually come with free private health insurance. It's worth checking as I think they changed the rules for foreign nationals, and you might have to pay or have insurance until you pay so much National Insurance from your income.
- Inflation is still fairly steady, and covid restrictions are minimal now
- We drive on the correct side of the road ?
- Places are closer together, you can travel across Britain in a day
- Milder weather, it doesn't rain as much as people say ?
- Full english breakfasts, roast dinners and Greggs bakeries ?
Cons
- Houses are smaller and the cost of buying/renting is pretty high depending where you live
- Cost of petrol/diesel is around £1.40 a litre ($6 a gallon)
- I think wages are lower or similar but the cost of living is higher than the US, and normal Income tax and Nation Insurance takes around 25% off your wage
- Roads around towns and cities get pretty congested
- Food comes in smaller portions
- People in some regions have thick local accents, so you'll probably need a translator ?
