Qatar Building deaths vs the Manhattan Skyscraper boom... double standards?

I have heard it said a lot online recently that 5000 people died building one football stadium in Qatar… This seemed to me to be a nonsense statistic so as the conspiracy theorists said I “did my own research…"

According to the Guardian “More than 6,500 migrant workers from India, Pakistan, Nepal, Bangladesh and Sri Lanka have died in Qatar since it won the right to host the World Cup 10 years ago…”

That works out at 650 a year.  The figure includes any migrant worker who died and had been building almost anything in Qatar during that period … not necessarily as a direct result of an accident or during working hours … 

“While death records are not categorised by occupation or place of work, it is likely many workers who have died were employed on these World Cup infrastructure projects”, says Nick McGeehan, a director at FairSquare Projects …vaguer and vaguer…

It started me thinking is this a fair comparison.  How many people died on other similar construction projects…?

So as a comparison I started to investigate how many people died building the skyscrapers of Manhattan…

Here’s what I discovered off the internet… the number of deaths due to onsite accidents was…

The Empire State Building 1,250ft high.  5 deaths.

The Chrysler Building 1,046ft high.  0 deaths.

The Rockefeller Center 850ft high.  0 deaths?

The World Trade Center 1,368ft high.  60 deaths.

The actual number of people who died building the Qatar World Cup Stadiums as the result of accidents is 3.

After some argument Qatar put the figure for overall deaths at 400-500 over I can’t remember how long … more arguments can be found here…While Le Monde suggests that there may have been many more deaths because it was hot and workers did not have proper heat protection … here ... but who is responsible for this ...?
