Being an expat still comes with tax obligations to the US, no matter where you live in the world. I moved to Germany but I still have to file US taxes every year unless I renounce my US citizenship someday. That’s one the most notable downsides that I can think of.
I’ll clarify. Not all the prices in Denver are going to be that high since Denver is large. My example from Speer Blvd was likely a worse case scenario since it’s downtown Denver. Not on the edge of the city limits like 9 mile.
You said you can’t imagine the prices being that different in Denver. In some parts, it is. The deals you posted at 9 mile are not representative of Denver as whole. Likewise with the more expensive downtown locations.
You could just look at their website to see.
As someone who grew up in the Denver area, here is some additional context. King Soopers is the grocery store that most people go to(Kroger owned). The Kroger brand eggs are the cheapest they offer and in the city they are $7.89 a dozen. In the suburbs $7.39. Downtown supermarkets are always a little more expensive. There are some egg brands priced at $10.99 and higher but the cheapest ones are still getting really expensive. And that’s if they aren’t sold out due to the shortage.
This show came on alongside another one called The Maxx which is also worth checking out.
