around how many percent of people think they don't need college degree to find a job

There's no way to tell. Who can get into every single person's mind and find out what each one is thinking?

To find an estimate of the percentage of people who think they do not need a college degree to find a job, you would need to refer to surveys or studies conducted on this topic. These surveys are typically designed to gather information about public opinions or attitudes towards higher education and employment. Here's how you can find this information:

1. Conduct internet searches: Use search engines like Google or Bing to search for survey results or studies specifically focused on people's perceptions of the necessity of a college degree in finding a job. Try using keywords like "percentage of people who believe college degree is not necessary for employment" or "public opinion on the importance of a degree for finding a job".

2. Look for reliable sources: When searching for survey results or studies, make sure to refer to reputable sources such as academic journals, research institutions, or organizations known for conducting reliable surveys. Government websites, educational institutions, or respected market research firms often publish these types of studies.

3. Analyze survey data: Once you have accessed relevant surveys or studies, analyze the data and look for the specific question that addresses the necessity of a college degree for employment. Examine the responses and calculate the percentage of people who believe they do not need a degree.

4. Consider multiple surveys: To obtain a more comprehensive understanding, compare findings from various surveys or studies instead of relying on just one source. This can help account for potential variations in methodologies or sample sizes, leading to a more accurate estimate.

It's important to note that the percentage may vary depending on factors such as demographics, geographical location, and the type of jobs being considered. So, consider the specific context and population being examined in each survey or study.
