The US has been campaigning against encryption for 30-40 years. The problem is that encryption has to be strong. Every time you weaken it, you leave yourself open to 'bad actors' who would like nothing better than to steal your identity, or drain your bank accounts, etc. The modern world relies on encryption for the world to work.

No encryption = no cashless society, no online banking, we'd be back to writing checks and we all know that they weren't particularly safe either.
