Niice,
okay.
What about these ones?
1) has and did are not parallel
2) did implies an action that held in past whereas "have" implies an action that is still going on.
Follow the sequence, if we are talking about "standard of living" that has been soaring since 1965, evident by the usage of "has", then the side-effects must also follow the same trend, must soar since 1965. If this is not the case then we can't put a relation between effect and side-effect.
Hope that has helped.
Do let me know if more clarification is needed.
