What makes you think that they care about the working class or lower classes? All they care about is themselves and their companies and businesses.
Some rich people only care about the working class because of the direct benefits that they get from them.
The moment that some of these jobs performed and carried out by the working class are now being able to be carried out by machine fully, many of these rich people who you think care for those that work for them in their factories and companies will be fast to lay off these workers because their first concern is actually their profits, the welfare of their company or business, not the welfare of the people that work for them.
That's the sad reality of life. How many have we read or seen that with automation comes with the lay offs of workers? This is why if your job seems to be replaced by robots or with automation, better think of alternative sources of income. So in case you lost your job, you have contingencies already in place. In this world, everything changes, so prepare yourself for the worst case scenarios.
