It's not even about "spending your own resources on others". Its about where the government spends YOUR money.

If I pay $100 dollars in income tax (for example), is the government spending that $100 dollars on MY healthcare, MY roads, MY sewage and water lines, MY roads.

Or is the government handing my $100 dollars off to private contracts who are then profit motivated to spend only $20 dollars providing those services so that they can keep as much of it as possible?

Socialism isn't "free stuff" or directly paying for other peoples stuff. It's about making sure the tax dollars are spent on US. When that happens, a surplus results that allows us to help others who are struggling.
