I'm not sure there's a country on earth that completely fits your criteria. There may be some particular areas that do but I doubt any whole country has those problems everywhere. Your view of the 3rd world must be quite poor.

I'd say that by definition a "3rd world country" can't be well off altogether. However, they can have a lot of "well off" people who live much better than most first world residents.

Funny enough, if we go by countries' wealth, isn't the U.S. the poorest country in the world?

Here's my first world problems:

1. My internet somehow dies out when it rains.
2. My computer can run Warframe, but it gives a lot of lag input.
3. My internet is catastrophically slow (2.5Mb/s), and I get killed everytime on online games.
4. I have a functioning air conditioner in my room I can't use.
5. I have many games and I don't know what to play.

This... is all pretty fucked up stuff.  

Watching Imocho, sound too high, neighbours think I'm watching hentai

Also too many games with psplus.

And i'm on 2 months holyday in France, bought 5 digital games for ps3, ps3 is at home.

Being abroad when friends of mine go to gamescom

#1.) Have to wash dishes because my sink is half full and I don't have a dish washer.
#2.) Have to wait until 5pm EST to play Destiny so I can get my exclusive Beta item.
#3.) Daughter wants to hijack my laptop so she can watch Youtube videos about toys.
#4.) Damn batteries in my TV remote died.
#5.) Forgot to cancel my Music Unlimited free trial and just got hit with a $9.99 charge.
#6.) My phone is an iPhone 4S from like 2-1/2 years ago.
#7.) The basement in my 3BR home is messy and I have to clean that too.
#8.) Yardwork, ugghhh...
#9.) Pissed that I have to wait until April 2015 for fucking Game of Thrones.
#10.) Have to switch out the upstairs A/C because the current one doesn't make the room cold enough.

That is my 1st world problems currently.

IDK, if you went by debt, pretty sure the U.S. would probably be the poorest

 Well let me add some third world countries for the sake of balance:

1- Very poor infraestructure: Ports, airports, railroads.

2- Horrible public transport system

3- No recycling programs.

4- Poor water planning. I mean, I live in a tropical country, in average we get 168ml of rain  per year, yet the politicians never thought about the growing population and the lack of water for some communities!! There is literally  4 hours of water per day! and thats been happening for almost a year now! There are some plans of making new diggings to find more sources of water, but that is just empty talk!

5- Rape-like loan rates for housing. When the minimum wage is $450, how can banks expect people to pay $600-$800 monthly for a house! (btw I am network engineer working for Cisco, yet $800 a month is still expensive for me)

6- Slow ass internet. Well recently is getting better. I have 10mb, but I pay around $45... I used to pay the same for 4mb.

7- Mobile internet sucks. LTE is available, but carriers do not subsidy phones the same way they do in other places. For example I got a huawei Ascend p6. I pay $32 a month for 4mb of internet (3g) but I dont get more than 1mb. So upgrading to a 4g phone such as Galaxy, Htc, Iphone or the likes will cost me around $500-$700 for the phone + the plan...

8- Eating healty is damn too expensive!! I do not eat fast food at all, (Last time I ate a burger at BK was like 10 years ago) vegetables, fruits, grains, fish, pork, meet is getting more and more expensive everyday!!

9- The gasoline is way too expensive. $2 a litre is overly expensive.

Didn't say they were. There is no country where everyone is well off. There are a lot of people in the US living in less than adequate  My point is some people think all third world countries are the same and have the same problems.

I thought that was common knowledge lol.
