Narrative:

On arrival into sat; houston center got back logged with traffic; and our sector controller was overwhelmed. It was apparent that he was not keeping up; and ignored several requests from us and others for a lower altitude. We were 40 miles beyond our required descent point; having previously been cleared direct to windu intersection; and the rodio 1 arrival. When he finally answered us; and approved a descent to only FL240; it was immediately apparent he had no idea what was going on. Shortly thereafter; he cleared us to fly heading 180; off the arrival; descend to FL230; and maintain 310 KIAS or greater; when a slower speed would have been better for everyone. Having proceeded south as instructed; when almost abeam the marcs intersection; he cleared us direct to marcs. This resulted in a slight right turn. After a few moments; the controller asked us if we were in a left turn. We replied that we were not; and that we were proceeding direct to marcs as cleared. In exasperation; the controller then commanded a left 270 degree turn to proceed to marcs. It was then that we guessed that he intended for us to turn to marcs the long way around; possibly to allow for descent; or for traffic sequencing; we never learned the reason. We requested a speed reduction to aid the sequencing; and were then handed off to another controller. When 9 miles from marcs at FL230; this new controller directed us to proceed direct to marcs; and cross it at 13;000. We immediately replied 'unable' due to the impossible descent gradient required. He then cleared us to marcs; and to descend to 13;000; without the crossing restriction. The remainder of the arrival was uneventful. My main concern in the event was that the sector controller was obviously under stress; and not handling the situation well. He performed as though brand new; or in training; if so; his trainer let things get out of hand. We followed all clearances as understood and read back; I don't want to be held responsible for not having read the controller's mind; when he apparently wanted us to proceed direct to marcs the long way around; but did not issue a clearance for it. I have no idea if traffic separation was compromised; as we certainly did not see or hear of any if there was. The entire evolution was an example of poor controller performance due to task saturation; I am very glad it was mostly VMC. As described above; the houston center sector controller was overwhelmed by tasking.better ATC controller training; and hiring controllers with flight experience. Unlike days gone by; I have been told that the vast majority of ATC controllers hired today have no pilot certificates or flight experience.
