Nope. Words have a meaning. Contributions are dedicated to a specific thing. Nobody can take the money of the Build-Hospitals contribution and use it to Build-Death-Star. Taxes however can go anywhere.

Once again, "payroll tax" is language invented by employers to make it feel like they're being unjustly taxed. Additionally, in the case of Europe, most of these contributions were set up after WW2 because employers were happy enough to collaborate with the occupiers and kept wanting cheap labour without participating in rebuilding nations. So, sorry, I won't cry about them having to pay their fair share.
