No. He and his team are incompetent. He tried to rule by decree, when that failed he tried to push a huge law and when that got pushback they tried to take it back to committee without understanding it meant they were back to square one.
Even so, blaming him entirely for inflation is silly. He's only the president, and has only had a couple of months.
That site is so weird. And whoever wrote that article is also mathematically illiterate. Not to mention they didn't link to any sources. So here is one they claim to have used:
https://ec.europa.eu/eurostat/statistics-explained/index.php?title=Foreign_language_skills_statistics#Level_of_command_of_best_known_foreign_language
This source says that 65% of 25-64 year old spoke at least a second language in 2016. The much lower number of 24% is when asked about proficiency, which can't be compared with the US given Americans' notorious overestimation of their own qualifications.
Most of the 25% of Americans (I couldn't find a source for this) claiming to speak a second language is immigrants. I guess it needs to be said, but when people comment on the monolongualism of Americans, it's about those who are not immigrants or first generation born in the US.
In my experience, most non Hispanics claiming to speak Spanish in the US struggle to hold even a basic conversation. And I have been to 35+ states, including door to door canvassing, etc.
