How do Thai people feel about the hundreds of single men from UK and America that visit for the girls in Bangkok and Pattaya?

Thai men don't care about those women.   They are only with foreigners for their money, not love.  Thai men are not looking for women who give themselves to any man.

they say give us Thai's your dollars as much

as you can

Right now, they miss them like hell, cause they used to bring a ton of money which they spent on hotels, restaurants, bars, tips, taxis, nightlife etc.

Whether they come for the girls or not, it doesnt matter, a lot of Thais wish they could live the way we do when we get there on holiday.  

I always brought girls over in every hotel i stayed at and no one ever seemed to be bothered as long as the money was coming in and no one complained.

After all the "supply" is much greater than the demand in Thailand nightlife districts, and its all geared towards single white men; for a good reason.

Most have a different outlook from how the situation is seen from a Westerners perspective. More like, it's seen as an agreement made between two adults and that's that. 

PS. there are also hundreds of men visiting from many, many other countries, not just the USA and UK ;)

There are no visitors at the moment due to COVID.

Thai people are desparate for tourists to return and boost the economy .

If you have got money and stay out of trouble then you're welcome.

ANYONE'S money is welcome. Even if you bring your own girl!!

Glad of the income I would imagine.

I wouldn’t blame them. There are some good looking women in Bangkok ;)
