Interested in Paraguay, what is this restricted list ?

Good advice.  If I might only add a little of my own experience in only three years living abroad and a total of five years preparing and researching before I did..... much of LatAm is approximately the same range of living and tax experience and my simplistic explanation to others that in LatAm economic life is about 1/4 of that in North America for instance meaning that a quality life that would cost $50,000 USD in North America can be equaled in in LatAm for 1/4 of that like $12,500 USD local equivalent.   What is different in my experience is that it is easier to 'get by' in LatAm that North America.   I mention this because the tax burden in every way is less than North America when you calculate all taxes not just income taxes.  North America has become a big tax-slave state and nothing more....you work to get by and the rest goes to the many many taxes in the day to day life in North America.   That is not the case in my experience in LatAm.   

My best example is the concept of simply buying a meal from a vendor in the street or a small cafe.   The odds are that when you buy a small meal or a quick bite in LatAm there is little to no tax on that meal added to the price.  When you take a taxi same comparison.  When you pay your Internet or phone bill etc.  In the USA everything effin thing is taxed at least once and many things have multiple taxes added to the price quoted.     This makes life for those on the low end of the income spectrum pay an inordinately high tax rate when all are added on.....and there is NO WAY to avoid it.    LatAm less the case.  IMHO

On the income spectrum....the % is somewhat the same.  A business that would generate $100,000 USD in sales in North America will probably only generate $25,000 USD in local equivalent.  So it's important to understand there is not magic in LatAm but I do find if you can adapt to a simpler life and take advantage of  the options that exist in LatAm you can have a better quality of life than North America on a month to month basis.

But sincerely this is just my opinion and my experience in owning a small business in Colombia for several years.   My point of sharing is to understand this and come to terms with it before one leaves to move to LatAm the first time thinking in the old mindset.

Lastly, let me say again this is just simplistic commentary and does not apply to every city like Rio or Bogota or Ciudad de Panama or San Jose  etc. as the big cities can be more like North America than I like to think about.  The saddest part is how the USA exports it's poor monetary policy and inflation onto the backs of LatAm because of their proximity/trade with the USA and required use of the USD for most international trade.   When I first starting visiting LatAm 30 years ago this was not the case.  Now the USD is a big problem for LatAm.
