There are two things you should seriously consider about todays science. Hardly anyone does any research or studying in any scientific field for free (gotta recoup those expensive educational fees, give that degree hanging on the wall some meaning) and no one funds any study or research unless they are in full control of the direction of this research and its findings and conclusions. With that being explained, you can probably assume that there are going to be some scientific findings that may not necessarily serve and benefit humankind as a whole and that these findings could even serve an alternative agenda.
Firstly, Here in Australia you can get the government to loan you the cost of your degree. You pay it back out of your annual tax return IF the degree gets you a job that earns you enough to pay it back!
Second, yes, industry pays for most of the research that is done primarily to advance that industry. But, in absolutely NO WAY are the findings/conclusions controlled in any way! Industry pays big dollars to do research and there is no point in lying about results, it does nothing to advance the field.
There are no bad results in proper scientific research, only results.
EG:
Science - The treatment group was shown to have no effect.
Industry - Great, we can stop wasting money on this treatment and try something else.
All findings are beneficial, many are disapointing but still beneficial.
