Retirement, healthcare, and taxes eat up a significant portion of a US earner's pay.

The amount of money that actually gets delivered to a worker's bank account could be a little as 2/3 of their stated salary.

And many things cost more here.

It'd be a good idea to work the numbers and figure out what your take-home pay would be and how your expenses would change. There are some expat websites devoted to this.
