Will European style socialism work here in the US?

Socialism is not even working very well in Europe where the genotype of the population is more conducive to socialism. The basic tenant of socialism/communism is that all the productivity of the group is controlled by a governing body and distributed equally and equitably among all. I know this is an oversimplification, but generally accurate. Even among a genotype that is industrious, intelligent, and less prone to crime, there is an attitude of "if I am not rewarded commiserate with my effort, why should I work hard"? In the US we have a significant percentage of the population that is less intelligent, non productive, and prone to crime, about 13%. It is my opinion that this 13% population is too high to even contemplate a socialist model. We can barely afford to manage and keep in check this 13% as it is now with about 75% of the population working hard and capable. If the productivity of the 75% falls at all, as it would under socialism, we would have a significant fall in standard of living. The 13% population will never be capable of significant contribution, even if they were motivated to work, they simply lack the intelligence to contribute beyond menial labor. I know that some of this 13% population are hardworking and intelligent, but if the contribution of these is off set by the negative contribution of the rest, as a group there is a net negative impact on society. I know this sounds harsh, but it is a fact we must address. As more of the traits of the hardworking genotype are infused into the 13% by intermarriage or otherwise, the negative traits of this 13% genotype will become less as the positive traits of the 75% genotype off set the negative traits of the 13% genotype.
