Pretty much every other country. In the UK for example, if you want to work, you just need to get a job offer. To keep numbers under control, they simply put a wage minimum that's high enough. Not fair for positions like nurses and teachers that are valuable to society, but generally ensure skilled migration. If you want to start a startup, a UK university can endorse your startup idea for a 2 year visa, and then raising a small amount of funding gets you 3 more years.

After 5 years of residence in the UK (except time as a student), you get PR, and citizenship soon after.
