The term is classical liberal. Capitalist is a strawman used by Marx to be some unrealistic thing they can knock down. Minimum wage is not compatible with the deep freedom message of of classical liberalism.
And mostly nobody is fighting minimum wage because it isn't a factor - you can't find someone willing to work for that anymore in most places anyway - which is to say supply and demand is working. They will fight increasing it because that is against the rules of supply and demand and ends up hurting the people who are the most disadvantaged.
Classical liberals were starting to fight against slavery before Mark was even born because it is not compatible with their freedom message.
Businessmen were against slavery before Marx was born as well - slavery is inefficient to a business. It is much more efficient to pay people to work and let them figure out how to get their own food and shelter. Slaves need to eat even when you don't have work for them to do. Because of this the classical liberal message of freedom was an easy one to sell to business owners since there was no cost to them anyway. (many businesses are of course inefficient and so you can find businesses that had slaves)
Your safe following distance on gravel at 50mph is more than that. 3 seconds is your minimum following distances on normal surfaces (used to be 2, advice has changed), you should have a 4 second following distance on gravel. https://www.drive-safely.net/safe-following-distance/
