What is the Marxist view of Handicapped people who are able to work to do work at Job

Of course. They're workers too, aren't they? If they're capable of working and want to work then they should be able to work.

What brings up this question?

I cannot speak for Marx or for most people on this forum, but in my conception of socialism, they most definitely would be accepted in socialist society. To use the most crude and elementary Marx quotation, a society in which goods are distributed "from each according to his ability, to each according to his need" would not imply that any fewer goods would be distributed to a disabled person. To be more theoretical, in late socialism/communism, the idea is that people should be able to choose which profession they want to enter, given the complete lack of commodity scarcity warranted by the material conditions of the time. This gives a disabled person complete freedom to do whatever they please, be it crafting things, computering stuff up, or simply appreciating the world passively. Socially, the jealousy some people currently have over handicapped people regarding their "special" status would be gone due to the relaxation of the economic pressures that prompted it in the first place.

I know I make socialism sound like a cure-all for social issues, but for the ones we currently know about, it more or less is. When you put an empowered working class in control of highly advanced industry, the potential is boundless. Granted, new issues will arise in the metaphorical socialist order, but they will be dealt with in their time.

I actually remember a quote from a video on teaching special education students we watched in my Teaching class. It was: "Fairness is not everyone getting the same thing. Fairness is everyone getting what the need."

Will this quote it's in a nutsell what is the main opinion of leftism about it:

They able to work? then they will work according with his (dis)habilities.

There are non-physical contributions to the social product that can be made by disabled people, like Stephen Hawking, that many able-bodied laborers cannot match. It is the same the other way around. Labor tasks can be divided accordingly. The key problem seems to be determining the true value of these contributions.
