barrywhiteismybrother I think resentful is the wrong word. Mostly we don't respect you.
My friend has a second home next to here, been in the family for 'generations' (forty years). It's good because it's empty, we can make as much noise we we like, they don't cause any problems most of the year.
It's bad because it's tatty, my friend has to keep any eye on it, just because she's a decent human. They aren't part of the community, no matter what they tell themselves. My neighbours kids are told to go further down the street for emergency help if they ever needed a neighbour. They don't contribute locally to clubs and societies, hairdressers, GP lists which impacts on the provision for hospitals which is why we don't want you here for a pandemic.
One second home in a street is fine, it cuts the traffic most of the year, but imagine lots, imagine being outnumbered. It's grim.
Holiday let's are also problematic. When we were in the baby stage, a friend rented part of a barn complex. The other six areas were holiday lets. Every weekend it was chaos with arrivals, every week it was someone's special birthday celebrated with a party, loud BBQ, a few fireworks. She wasn't resentful, she doesn't know you, she didn't give a shit it was a special birthday she just wanted to get a baby to sleep.
I don't know what the answer is, everything in moderation, narrow the wealth gap. It's not even a Cornwall Vs London arguement. Look at the chaos Airbnb has brought to Barcelona and other major cities.
We're not resentful but don't think we respect you.
