That is a capitalist, neoliberal attitude at best. It is particularly popular in the USA, where children are taught to evaluate reality in quantitative terms. It is extremely important for US capitalism to promote this view of humanity, because it legitimizes the major social hierarchies in this society. It also legitimizes why children are allowed to go hungry, the poor are denied medical care, and other countries are exploited. After all, they are not worth it, otherwise they would not be in this situation. In the worst case, it is therefore the basis for right-wing ideology in the USA.

But ultimately, it is a normative decision that everyone makes for themselves. I cannot convince you with arguments. If you believe that people are fundamentally worth different amounts, then probably no argument can convince you otherwise. I can only say that I am glad not to have anyone like you in my circle.
