oh really please go get us some of the information on which you learned this?
For the UK:
HM Revenue & Customs: National Insurance for employers: the basics
As an employer you pay National Insurance contributions (NICs) on the earnings you provide to your employees.
That's the first sentence about employer's paying NICs. NICs in the UK are used to fund its health care. Both the employer and the employee pay. That is standard in most countries with 'universal health care'. Idiot.

National Insurance contributions - employers' responsibilities
Broadly speaking, National Insurance contributions (NICs) are payable on employee earnings, including non work related expenses and provided benefits. There are different classes of NICs that apply in different circumstances. Some are paid by both employers and employees, some by employers only and others by the self-employed.
As an employer your main responsibilities are:
•
to deduct and pay the employer and employee Class 1 NICs due on your employees' earnings through your payroll
• to pay employer Class 1A NICs after the end of the tax year on benefits you've provided to your employees
• to pay employer Class 1B NICs after the end of the tax year if you've agreed a PAYE Settlement Agreement (PSA) with HMRC
If any of the people you engage to carry out work for you are self-employed, then they're responsible for paying their own NICs (Class 2 and Class 4).
