You know what actually dissuades people from starting a company?
Not having any money to invest. No savings. Due to poor wages.
Can't get a business loan due to interest rates and general bank sentiment of the past couple decades which is to not give out small business loans because they're high risk.
Can't take the risk of putting everything you own into a business and risk being homeless if it fails.
Plenty of employers will not be impressed by candidates who have attempted to start a small business. Smart ones will see it as hugely valuable in a candidate, many will think they're too ambitious. Small business owners don't trust them because they're paranoid and think they'll have ambitions to come after their business somehow (small business owners have their own weird class of dumb myths they believe, including the false belief that unemployment comes from their pockets and not state taxes, they get fleeced by lawyers constantly who make them fear everything). Managers at big businesses often fear ambition because they're paranoid because they are the backstabbing ambitious type and so they're afraid of anyone else who can stand up for themselves.
Trying to start a business could tank your career if you fail. Especially if that business was outside your career field. E.g. trying your own software startup as a software engineer, good. Trying to start a non-software business as a software engineer, bad. It'll be seen as "they couldn't hack it in the field so they did something else." Ask me how I know. I have my own failed company and I am careful to place it on my resume because some people react negatively to it. The past FAANG experience is apparently irrelevent. It's insanity.
Starting a business in the US is incredibly risky. For decades all the socialized capitalist countries in Europe have had 2-3x the rates of entrepreneurial success, at least. It's a lot easier to take the leap of starting a business when you know society has a safety net that'll stop you from becoming a damp mark on the pavement should you fall.
It's insane how anti-small business America has become.
