I suspect both are true, for different types of patents.

Tons of low-quality, generic software patents are good for extracting small settlements. Especially when the firm wielding said patents can dissolve and reform overnight to dodge negative judgements, there's very little downside.

Separately, funding serious research purely for the purposes of creating high quality patents does not seem like a winning proposition.

Unsure of where creating patents in the normal course of business and using them for M&A leverage or for tit-for-tat deterrence falls on ROI scale.

Undocumented immigrants increase the supply of labor, and therefore applies downward price pressure. If you are someone who trims/removes trees, reducing this foreign labor arbitrage is a positive. (While undocumented immigration may be a positive for efficiency/economy as a whole, it certainly is not if you are facing increasing competition as a supplier of a service)
