Classic Doctor Who proves you wrong.
If the BBC hadn't fallen under the control of a clueless fool it would have never gone into hiatus. Sadly the video by Sfdebris that explained the whole ClusterFUBAR got clobbered in the moving from video service provider to video service provider as he couldn't really put it on Youtube as that site is seemingly run by overzealous neurotics. Thankfully, Screenrant's "
Why Doctor Who Was Cancelled In The 1980s" hits some of the same points
Classic Doctor Who showed that even if its budget is borderline nonexistent it
can compete with a far richer country like United States. Heck, Classic Doctor Who had less of a budget than Original series Star Trek!
In fact, the Star Trek comparison is not that far off as one of the ways Classic Doctor Who was killed off was putting it in a time slot totally unsuited to its audience though in Classic Doctor Who's case it was also run it against one of the most watched shows of the period. You listen to Colin Baker's Big Finish outings like "
City of Spires" and "Wreck of the Titan" and realize if he had been given good scripts he would have been a decent Doctor.
Produce good shows with good scripts done by producers who know what the sam hill they are doing and you will succeed even with a poor budget. Pull the kind of crap happening with Doctor Who and Star Trek now and you will not only kill your golden goose but make it to the point that another revival is unlikely no matter how much money you throw at it.
