BroI agree with you Bro that India is one of the best place to live. Even no one thought of living India and always dream to be born again in India.
People know the best way how to live with limited resources. But as you mentioned people of older ages also working after retirement for their living same is happening in India also in urban areas after retirement from government they work in low end jobs . I am strongly opposing such kind of work because by doing such kind of work won't bring happiness to them as well as to economy since we are having huge young unemployed people who are wondering here and there for search of job but due to occupying jobs by older people at low wages also hurting youth and not able to groom their skills in the jobs but you see people of older age working every where in India.
Even Government of India also raised the retirement age from 58 years to 60 years and now also planning to raise the age due to some benefits but if government discourages such practice of employing people after 60 years old then we would increase employment of 10 million every year.
After 60 they can do business, consulting services, social services, education , cultural so on but not of labor work or other unskilled jobs.
And Should have strong social security system where older people will be taken care by society.
I would rather say it is because of more and more unlimited wants and limited resources. Since people are more and more on focusing on material world.
For fulfilling such demands they require huge money other wise In India cost of living is very less.
Cultural aspect

Must be strong !
In Indian culture children of older people always take care of them and sons always live with them in case of daughter who is married, takes care of her husband's parents.
So its very strong family bonding . Some of the case where younger people have to live parents due to jobs and working in other cities they tend to leave their parents but always take care of .
Its like if they don't take care of their parents later they will be treated the same by their children since the teaching goes one generation to an other.
And in our culture always emphasis on these values.
Bro its our inner feeling about some thing based on the environment. Since the population of Latvia is very small and forming opinion of one takes lots of struggle inside and out side the world since people from other world always provoking that their system and believe are the best and just adopt these other wise you will face consequences. So you see its better to adopt others but in general Latvian people are wonderful who love their country , language , culture and take every step to preserve this amazing ethos of this country.
I appreciate them, there are only few countries in the world who are doing this as you see in the history most of the world best cultures and languages submerge with war and ravages.
But Latvia is truly preserved and I always pray god Latvia always have stronger views and always preserve what their ancestors had created
Warm Regards,
