1000LSK balance will earn you a reward of 7+ LSK a month if you just spend 2 LSK voting for GDT, Sherwood, and a few Independents. $2000 for 1000 LSK gives you a $14 return each month which is better than most bank accounts. Really we need more delegates like Sherwood that are forging. Sherwood takes up 6 votes and only has about 3-4 that are forging. 4 delegates is about ~1/25th of the 101 forging delegates. If all the delegates were all like sherwood you would be earning 100+ lisk a month for voting with 1000LSK. That's why I only use 2 LSK to vote and refuse to vote for any delegate/pool sharing very little rewards.

Yes it's true that voting for a delegate sharing 20% who is forging will yield you more rewards than voting for a delegate who would share 70% who isn't in a forging position. A lot of people have that mindset, and it causes those 20% delegates stay in a forging position. If those voters changed their ways... their 1000LSK could have double the impact. (1000 LSK voting power removed from a delegate sharing 20% and 1000 LSK voting power moved to a delegate sharing 70%)

I'm hoping the system changes in the future. Maybe they will allow for more delegates, or maybe they will make delegates sit out after X turns unless they share a certain amount. Either way, if you have 1000LSK definitely vote. I think it's worth spending 2 LSK to vote as long as you have at least 300LSK (Currently $600 investment). Keep in mind if you believe in LSK, now is the time to be accumulating. Imagine your 7 LSK return from voting rewards when LSK is back up to even half of its ATH.
