If we give the government the ability to appropriate funds for social programs and safety-nets, rather than merely enforcing the rights in the constitution, it is inevitable that these funds will inevitably be misappropriated and allocated in ways that benefit the politician and his buddies, primarily.

As we continue on, we discover that, lo and behold, the programs need even more money, time for a tax increase!

Further down the line, we discover that further tax-increases are not politically-viable... no problem, let's just add to the entitlement-burden and let's re-visit the issue.

Later still, it's time to start paying for those unfunded liabilities but, damn it, there's no money in the vault. No problem: let's just print more money, and while we're at it, let's loan it to ourselves and charge "ourselves" interest (the second "ourselves" of course means "taxpayers, LMAFO).

Repeat until your currency, economy, and society collapses.

Other nations have no problem funding social programs, because they maintain a reasonable tax rate for high-income/high-wealth entities and avoid expensive indefinite foreign wars.

Keep in mind that a lot, if not all, of those countries exist under the umbrella of protection that the United States military provides, and thus do not have the same budgetary requirements for their own forces. Otherwise, time to start learning how to say "Please don't shoot" in Russian.

(edit: don't take the above as the complete-picture, by any means, it's just another rarely-mentioned factor that I wanted to bring up. I believe there's a sweet-spot to be found for taxation & social-programs that has a net-gain for society.)
