That's the most tragic part of our two-party politics. The neoliberal democrats hesitate on funding universal healthcare/etc, but they're also perfectly fine with funding and justifying war. The Republicans talk good about government expenditures, then mums when you start talking about war spending. Infinite war spending is perfectly fine for them, and they even think we're not spending enough!
The funny thing is that many of the things like have universal health care (cost one third per person than what we have now, based on examples from UK and Canada), basic income with supported housing (which would be much cheaper than leaving the homeless out there, and invigorate the economy), etc would actually save the country money.
