That's one way of looking at the West. One way to curtail illegal immigration to the states and Europe is to have a way for many people to get out of poverty. When people make a decent living, they won't uproot themselves to move to the US/Europe.
In states such as Andhra and Telangana, there is a public distribution scheme, which supplies subsidized rice and cooking oil for a long time, at least since 1985. Even in 1985, they supplied 1 kilo rice for 2 rupees--this price is kept that way even today. Families get like 25 kilos per month. For many, that is a savior, even though this rice is not of quality (like sona masuri, basmati). However, it is tasty when the rice is freshly cooked and hot.
After PV Narsimrao's reforms, thanks to IT and service sectors, many people are able to get out of this dependency. In South India, every small village has many people working in Chennai, Hyd, Bangalore, Pune for many IT companies, etc.
In Late 90's and early 2000's, even if you were a M.Tech graduate from IITs in chemical engg/civil engg/mech engg, Companies like Infosys/TCS did not hire such people. Today, same companies go to a third rate private engineering colleges, hire a lot of people for jobs.
Now, you see a lot of migration from the North to the south--to work as carpenters, electricians, etc. Also, population growth is kind of slowed in the south--at most two kids per couple.
All consultancies (IBM global services, TCS, Wipro, Infosys, Tech Mahindra, Deloitte, Pwc, Accenture, etc) just want billable hours. Only way to make a fat profit: by underpaying. Who will take "less" pay? Of course, less qualified people. Since every consulting company is doing this, there is no incentive for big companies to switch from Infosys to TCS or from TCS to IBM.
Hiring managers do get kickbacks from consulting companies. These kickbacks are sophisticated, and there is no way to prosecute them, esp if immigrants are the hiring managers.
Here is a tip: just inform the interviewee that because of "hiring fraud", the whole interview video will be recorded. Such frauds won't accept your job offer, even if they clear interviews.
Even the law is 'founded' on the monopoly of state violence within its borders. Extend this logic to the whole world: whoever has more power to inflict violence has the 'legal' authority. Law without the monopoly on violence is toothless.
