If by 'crashing the system' you mean refusing to approve yet another massive spending bill and thus "shutting the government down," it is the only means either the President or the House has to control government spending. The reality, of course, is that the government doesn't "shut down." Checks continue being written, the military continues doing its job, etc...the only thing that really shuts down are public services, like access to national parks, and even they are only shut down to pressure the public into doing this or that. In the current instance, Trump is said to have really hated the CR passed by Congress, but Speaker Boehner talked him into signing it...from my perspective, that was both sad and stupid...sooner or later, the fiat currency madness will collapse the system, and I had hoped Trump at least had the balls to send a strong message to the American people that "enough is enough." Here's a classic example of "fuck the public, spend spend spend: Democrats: We Need to Raise Domestic Spending Caps --no, you morons, we need to STOP raising the debt limit and live within our means.
