What do programmers actually do?

2mln  peolple watched  this video .
If we will think logiclly labour market is not in condition to satisfy and give vacancy for every one .So if software devs now earn 70k 80k then in near future (2 3 years ) it will fall to50k 60k.High paid jobs will be lawyers  jobs in healthcare mech.engineers. and other and not programmers.also as u see there arising constructors like in aws .wix wordpress.and high competition for 1 place or 1 ordered projects from investor  in usa  are compiting from india ukrain russia and usa itself .and I as a analyst i can say this job will fallndown in 3 4 years . If u dont believe it i can even show it to u using predictive  mathimatical modles (calculus) .if u are programmer from usa or europe or russia or ukrain so u should not become a programmer because for ur job  that u want to posses in future programmers from india china central asia are ready  do this job for much cheaper 
For example. in usa if ur going to do a projects for 1000000$  by employing front end and backend  and designers  u can do the same project in india or in chine or other country for 20000$
